Rusthe whether gold in the ground rust. Whether gold is oxidized. The best samples of mineral
Is gold rust? You can find out a scientifically based answer. Thank you. And got the best answer
Answer from Yegor Akhryapin [Guru]
Rust is called metal oxide (or a mixture of oxides) in air, gold does not change its color and does not interact with oxygen even when it is heating to 400 ° C. Under normal conditions, the gold surface is covered with the finest adsorbed layer of oxygen, but directly, even when heated, gold is not connected not only with oxygen, but also with gray and selenium. AU2O oxide and AU2O3 oxide can only be obtained indirectly. Equipment: Gold does not rust!
Answer from Max[guru]
Is it only oxides with time, as no whole metal .. Therefore, it can be noted that gold burns, it is brighter, and so on, etc.
Answer from PASHTET (Pasha888)[guru]
No, because under normal conditions, at an average of 25 degrees Celsius it does not oxidize as iron
Answer from Alexchem.[expert]
Definitely - gold does not rust! And it does not oxidize. In the inevitable conditions, as the previous speaker noted.
Answer from Vadim Kotov[guru]
What does rust mean? So they say only about the gland. Even nickel and cobalt say that they are oxidized in the air. Copper is also oxidized in air and in some cases the presence of moisture is covered by protecting the metal from further oxidation and destruction of the noble patina. Whether gold is oxidized in the air is practically no, although it is indirect that you can get a reddish oxide, and a purple gold. In general, with a fluorine, you can oxidize gold to the limit 8 valence state. Recently, a compound 7 of valence gold was obtained, for oxidation by fluorine some with difficulty fluorinated compounds. In general, using photonuclear reactions occurring inside the melt with an arc burning inside the melt, such as iron, you can pass the lannoid compression of gold, and it is better for this purpose to use tin, lead, mercury. This problem was still engaged in the Union of the Uncooked Professor of Bolotov.
Answer from Dmitry D.[guru]
what, on horseback, oxidizes if gold is found in nature in the form of nuggets or golden sand. What do you get the prospectors? It is there millions of years lies - and nothing!
Answer from VD.[master]
Gold does not "rust" because it does not interact with oxygen. And does not interact with oxygen, because the valence electrons occupy such conditions in it, which is more profitable by energy than if they switched to oxygen. And in the gland, the opposite is the opposite. So it's all about the electronic structure.
Answer from Alekx ku[guru]
chemically not active, resistant precious metal as all metals has the property oxidizes (rust oxide) so that it is necessary to oxidize the condition, in the natural environment, (conditions) oxidation as well as the reduction of oxide does not occur energetically unableless processes (balanced) enthalpy does not change so much There was a shift (direction) of the process
Until now, on the Internet there is a rapid discussion of the situation on the monetary courtyard in St. Petersburg, when "Georgy Victorious" released by this yard, suddenly, rust began to manifest. Scandal that you say here! What? And here steal!?
"Yes!" - Stills of the TV channel Rain, a well-known Russian businessman and a public figure Herman Sterligov.
But is it really?
A very serious investigation was conducted and everything was resolved the most prosaic way. It turns out the case in imperfection, or rather, violation of technology. Part of the metal chips, literally microns, as a result of non-compliance with technology, fell to the surface of coins. Over time, this "gold" and began to be covered by stains.
But, in fact, with such behavior of gold coins, investors are not faced for the first time. Periodically, the press services of banks report on the perturbation of their clients, who after the year of storage in the cells of their gold coins, suddenly, take them to "rusty stripes". Such cases were stated by the employees of North-West Sberbank and Khanty-Mansiysk Bank.
As for the defects themselves, it must be said that this problem is not new. Periodically there are separate batch of coins, on the surface of which after 2-3 years (depending on the storage conditions) there are various turbidity, changes in color or reflective properties. All indicated changes are nothing more than a defect of production, and superficial. The reasons for its appearance are most likely to lie in the ingress of foreign chemical impurities to the surface of the stamp, possibly when it is purified, although it may be possible to give more detailed information, probably only milling yard technologists.
Head of the Office of Operations in the Financial Markets "Rus-Bank" Stanislav Philippov
The situation is very unpleasant, so the banks seek not to advertise such incidents. The main thing is that the problem recognizes our chief - Sberbank, accusing its partners in the desire to "not bear sorrows from the hut."
The reasons are nominated very different. The resulting errors in the production are obvious. But it turns out some believe that:
- Considering the state of the atmosphere and its influence on everything around, after 5 years of storage of traces on "gold" anyway can not be avoided;
- We are just bad my hands, and the sweat contains urea and fat, adversely affecting the surface of coins;
- Not enough clean storage conditions.
On the other hand, if you consider the chemistry of all processes, and after all, "Georgy Victorious" was produced from gold 999-oh, the highest, samples, then the present reasons should not be in principle. If the gold coin came out from the courtyard in perfect condition, it should remain on the century.
All these conversations about the sweat, urea and fluorine toothpaste are ordinary excuses and the desire to bring the shadow on the woven.
Yes, cyanide compounds, bromine, mercury affect gold, but so do not let God meet in ordinary life, lacked for our hands in mercury.
In scientific speaking, Patina and gold are completely incompatible things. If there is a patina, then problems with gold, and not in some mythical reactions "from the press services of banks."
On the other hand, there is no doubt - if it is announced that the manufacturer used 999 sample, it means that it is.
Conclusion one, to which, even hope, all bankers come: rust - a consequence of the technological process of manufacturing. We started, striking and weighing all the opinions, making a circle, to the same and came. Cannot say: "steal-s, gentlemen!" (Even on the Mint!). But what is working, and here, after the sleeves are no doubt.
It is necessary, just to note that the Central Bank at least recognized the error, but it is not in a hurry to correct. At least the scandal broke out in 2010, but the rust on the coins of the St. Petersburg Mint (SPMD) appears on the coins of 2015. Justice for, it must be said that in a much smaller scale. By the way, it is precisely that a slightly understated price is due to the products of the Moscow Mint (MMD), where such a marriage was not observed.
What if your coins were covered with "rust"?
First of all needs to calm down. Your coin is absolutely genuine and contains exactly so much precious metal as indicated.
There is no other terrible in these stains, they are superficial, easily removed by simple chemicals, and practically do not affect the sample.
Head of the Department for Work with Precious Metals Bank "AK BARS" Azat Salahutdinov
Spots can be eliminated. Only it is not recommended to do it yourself, without proper experience and knowledge you can only aggravate the situation, which will lead to a real decrease in the cost of the coin. It is best to contact the jewelry workshop where the coin is cleaned quickly and safe way. The average cost of the procedure for cleaning one gold victorious 50-100 rubles.
You can leave a coin in the same condition. Most investors are already aware of the causes of the problem and do not focus on it. And the difference in price between the "normal" and "defective" coin is 200-300 rubles. And sometimes it is not at all.
First of all, I decided to go to Sberbank and find out why such spots on gold coins appeared, and will they take a coin into a buying.
A large stain near the letter "I", as well as on the edge of the coin you can see other spots.
In Sberbank, they said that the coin will be accepted without any questions. Not a hindrance, because the Central Bank released an order in which coins with spots are equal to the coins of an excellent condition. The main thing is that there are no spots on the coin. More important: at the price of gold, they only bother the victorious and Sochi rectangular, the rest are considered not investment. And for my coin 50 rubles 2015 Sochi hockey, I was offered 16,500 rubles, which is currently below the price of metal in the coin (7.78gr. * 2600r \u003d 20228r - the price of metal). Therefore, to take it into the buyer of Sberbank - no sense.
About origin spots on gold coins I was answered that this is a technological problem.
Theory 1:
I am satisfied with the campaign in Sberbank. But continued the investigation. On the Internet, I came across a very interesting version, it says that the appearance of such spots on gold coinsmay be due to the fact that on the mint, a stamp which coins coins, is not fully cleaned, and that particles of other metals remain on it. These most particles are imprinted in gold coins, and just the same these metals remaining on the surface of the coin of gold and oxidize, as a result of which spots similar to rust appear. This theory is quite interesting, I think it has its own foundations.
In order to be confident 100% and dispel all sorts of doubts, I will take this coin to a special laboratory, where to analyze its composition. In order to make sure that the metal is purity and the fact that the coin really consists exclusively of the gold of 999 samples, we give a coin on the examination, where it is carried out x-ray, fluorescent analysis over it. This method used to determine the concentration of elements in substances of various origins. Performs accurate measurements at high speed. It is based on the collection and subsequent analysis of the spectrum arising from the irradiation of the conducted by X-ray material. I would like to note that this method of determining precious metals does not destroy and does not damage the coin. The error of the device is up to 0.5%. Such an analysis is carried out, for those who are interested, it can be held in the State Historical Museum, for a certain amount of money. So, the analysis showed that the purity of the metal is 24 carats, and this is the maximum purity, the content of gold is 100%, with an error of 0.3%, that is, a mint, Central Bank and Sberbank do not deceive usIn this case, this is no admixture and not dirty metal, but a pure gold 999i sample.
Theory 2:
In the process of our little "investigation," we talked with one of the leaders of one of the largest jewelry factories in Moscow, which manufactured gold medals of the corresponding sample for the 2014 Olympic Games. He confirmed the formation of orange dots on gold. It was revealed that it was not to blame for a metal, but plastic capsules, in which these medals were placed. After detection "Rust" on goldJewelers got medals from the capsules, washed with a special chemical solution, the stains came up with them, packed back, and after only three days, the stains appeared again. In my case, there is no labeling on the capsule, the manufacturer is not known, so it is impossible to exclude the possibility that in spots on gold coins Blame plastic capsules. Cleaning the coin, unfortunately it is possible, since the coin of the quality of PROOF, and will be hopelessly damaged, because it will lose shine.
However, Sberbank will buy this coin even with stains (for them spots on gold coins Not an indicator, as the Central Bank ordered, so that Sberbank took coins with these spots), but Sberbank will buy them at the price that is indicated in their price, in my case it is 16.500 rubles, but it is not profitable for me, since the price itself Metal at the moment is more than the price in the price of Sberbank. I found on the Internet sites that buy gold coins at metal prices, so if you urgently need money it is more profitable to sell the coin there. They also take and gold coins with stains.
Anonymous components of gold alloys determine not only the color of the metal. The durability of the jewelry largely depends on them. What gold is not rust is a myth. Another thing is that the presence of silver alloy, palladium or platinum gives it additional resistance. Okhydrate metals, on the contrary, make it an order of vulnerable.
The most common manifestation of corrosion is the darkening of gold. But there are more dramatic cases. It happens that the wedding rings in the literal sense of the word fall apart. By the way, at all times it was considered a bad admission and foreshadowed the collapse of marriage. The chains are even more often breaking - especially in the locations spa.
Corrosion is noticeably accelerated if the product is placed in an unfavorable environment. The active corrosion medium is the usual human sweat. In addition, in the "Black List" - Red Wine. It has long been noticed that this drink is able to rapidly dissolve the layer of gilding on the church bowls. And finally, various detergents. Surface active substances that are certain in their composition may be destructive for any jewelry.
But the main reason for the rapid corrosion of the jewelry is technological disorders in its production. An arbitrary change in the chemical composition of the alloy, the presence of extraneous impurities in it - almost one hundred percent probability is deprived of the Gold of Durability.
The best samples of mineral
More articles on the topic:
- The nuggets are customary called natural pieces of metals weighing more than 5 - 12 g and the size of the diameter is more than 4 - 5 mm. From a geological point of view, gold is an ordinary rare metal, what a lot in the Mendeleev table. And from the standpoint of common sense, it cannot be compared with such grants as aluminum, nickel, cobalt, copper.
- Jewelry of yellow gold - hit the current season. Gold - Symbol of the Sun and Luxury, King Metals and Metal Gods. His story, washed with countless legends and myths, leads us to the moment of the origin of human civilization. Gold as the most precious metal has been published by a monthly equivalent in trade, and therefore there are methods for making gold-based gold-based alloys. Russian gold mining on an industrial scale began its existence in the Urals. Then began on Kolyma. The first gold discovered by a person was most likely to be on the surface of the Earth. Then the man realized that he could be found, splitting and turning around pebbles in the valleys of rivers. Currently, gold is mined mainly from ores, and not only gold, but also, in which other non-ferrous metals are the main minerals, in particular copper, zinc, silver, lead. In this case, considered as a fellow traveler. Gold in nature is found both in the fields of purely gold and in the complex with many other related non-ferrous metals in geological terms. The rarity of gold during its unatarked beauty made it a precious metal (precious stones were selected according to the same signs). In the first states of Egypt, two-frequencies, America relatively quickly gold became the property of rulers and nobles. Probably gold is the most beautiful of all chemical elements; It is known to people and appreciates with ancient times. In nature, gold is usually found in the form of a metal, and two ways of its concentration are known. The presence of dissolved gold in seawater was established in 1872; Numerous attempts to develop a cost-effective method of extracting gold from sea water to success did not led gold from alluvial precipitation with the help of a gravitational method already known, at least 6,000 years ago, the product of gold necessarily has a stamp indicating the sample of metric or carat. The sample is the amount of pure gold or silver in one gram of metal. If the product is stamped by one of the Russian test inspections, it is possible to be relatively calm for its origin. Of course, provided that the stamp present. In Russia, many copper are traditionally added to the gold alloys, which gives gold a pink-reddish tint. But in the Scandinavian countries there are so pale gold that the yellowness is slightly noticeable in it. The three most famous colors of gold - "red", "white" and "yellow", "red" is our native, inherited from the Soviet, and to be completely accurate - even with pre-revolutionary times. With all the banality, this rule can be considered universal. About the beneficial effect on metal expensive additives in the form of platinum and palladium has already been said. In addition, the higher the sample of the gold itself, the greater the guarantees that over the years it will retain its trade look. Low mountain range Withersrand (or just rand) is located in South Africa, in the province of Gauteng. Withersrand is the largest gold deposit in the world - more than 40 thousand tons of precious metal have already been extracted from its subsoil.
A selection of materials for those who are interested in the topic:the appearance of "rust" on gold coins
!
A source -http://wzascok.livejournal.com/6505.html
To me as a former chemistry, this topic was also interesting, especially since he had inherited a rather impressive collection of coins.
True, I did not have to see the victim of rusty gold coins, although such enough, maybe it was before the gold was different? ... at least I have never met rustynikolaev Gold Chervonsev, and Rusty Golden Finnish Stamps The times of the Russian Empire ...
Well, in general, read, draw conclusions, my opinion is thatthe reason still lies both in the stampe itself and in the technology of stamping coins.

Recently, information about the "rusty" Golden Coins "Georgy Victorious" periodically began to appear. Sometimes they say that Patina appeared on the coins "Georgy Victorious". The first thing about this phenomenon was told several months ago the entrepreneur Herman Sterligov. He published photos of coins, on which spots are clearly visible, the color of which is different from the color of the coin. Finnews.Ru decided to figure it out in this problem and found out the following.
Is there "rusty" coins?
Only a few of the surveyed banks admitted that their customers were faced with the problem of "rusty" coins. The press service "Sberbank of Russia" reported: "There were cases when" victorious ", having, most often, red spots and / or bands on coins, were brought to the return purchase in Sberbank, but did not give them away because of the stains, but Just like coins. " The press service of the North-West Sberbank said: "Yes, such coins are found." The press service of "Khanty-Mansiysk Bank" said: "In one of the branches, the client kept them in a bank cell. It came to be taken, and on them" rusty "stripes.
Other banks (including playing a significant role in the market of precious metals) or denied the presence of such problem coins from their clients, or ignored the questions of Finnews.ru. Since the largest player of the precious metals market (Sberbank) recognized the existence of a problem, the silence or denial of such a problem by other banks testifies either about the insignificance of their real role in the market of precious metals ("rusty" coins not much, so they have not yet come across such coins ), Either about trying to hide your head in the sand.
What do bankers say?
Some banks made "household" assumptions about the reasons for the appearance of "rust" on gold coins. So, in the "SMP Bank" suggested that "this is" Patina ", it appears after 5 years of storage, like on jewelry with a long storage period. Clean it, like decorations, special composition. In the north-western branch of the bank "Ak Bars" suggested that "rust - gold oxides (chemically pure) from contact with hands, which are not perfectly clean. The sweat contains a lot of urea. A lot of things can be on your hands after we took everything around Himself, cleaned teeth fluorine paste, or touched mercury containing batteries. Clauses of the sea. " Head of Plastic Card, Commission, Savings and Investment Products "Absolut Bank" Elena Novikova said: "It is not recommended to touch the coin with hands, since the finger trail left on its surface (especially on the mirror field) is practically not to be removed. Even in The case of successful cleaning of the track is not excluded that in front of the first glance, fat residues will enter into a chemical reaction with the composition of the coin surface and the oxidation spots will appear in this place. " In the Bank's cash circulation department, the Bank of Russia stated that "in some cases, depending on the storage conditions, there may be spots, which are oxides of metals and microscopic particles of various substances falling onto the surface of coins. The presence of stains does not characterize coins as defective."
To understand how much these assumptions correspond to the truth, you need to refresh knowledge in chemistry. Those who studied well at school and / or institute may not read the next chapter. For the "victims of Fursenko" let's notify the following.
Scientific information about gold, rust and patina
In the same department of cash circulation of the Bank of Russia reported that "Golden coin with a nominal value of 50 rubles" Georgy Victorious "is a coin of investment value, a mass of precious metal in purity - 7.78 grams, gold test - 999". Sample 999 means that in one kilogram of coins will contain 999 grams of gold and only 1 gram of impurities of other metals (as a rule - it is silver and copper). What does science talk about the physical and chemical properties of gold?
Pure gold is a soft metal yellow color. Gold is very carpet and hard (for example, from a piece of gold weighing in one gram can be pulled out a wire length three kilometers or make a gold foil 500 times thinner of the human hair - 0.1 μm). The softness of pure gold is so great that it can be scratched with a nail.
Gold - the most inert metal, standing in a row of stresses to the right of all other metals, under normal conditions, it does not interact with most acids and does not forms oxides (allocated by the editorial board), due to which it was assigned to noble metals, unlike the metals of conventional, easily destroyed under the action of the environment. Gold soluble from pure acids only (allocated by editors) in hot concentrated selenium acid: 2AU + 6H2SEO4 \u003d AU2 (SEO4) 3 + 3H2SEO3 + 3H2O. In aqueous solutions of cyanides, in the access of oxygen, gold dissolves, forming cyanoarata: 4AU + 8CN- + 2H2O + O2 → 4- + 4 OH-. With dry chlorine, gold reacts at ~ 200 ° C with the formation of gold chloride (III). In a concentrated aqueous solution of hydrochloric and nitric acids (tsarist vodka), gold dissolves with the formation of a chlororat-ion at room temperature: 2AU + 3CL2 + 2CL- → 2-. Gold easily reacts with a liquid bromine and its solutions in water and organic solvents, giving a tribromide AUBR3. With fluorine, gold reacts in the temperature range of 300-400 ° C, at lower temperatures the reaction does not go. Gold is also dissolved in mercury, actually forming a low-melting alloy (amalgam). There are gold-corneal compounds (for example, bromide diethylsolot). All alloys above 750 samples will not fill in the air (that is, they are not covered with thin film oxides, approx. Ed.).
What is rust? Rust is the domestic name of the result of the process of corrosion of various metals. Corrosion (from lat. Corrosio - corrosion) is spontaneous destruction of metals as a result of chemical or physicochemical interaction with the environment. From the point of view of chemistry, rusting, for example, iron is oxygen corrosion of iron in water: 4Fe + 6N2O + ZO2 \u003d 4FE (OH) 3. Hydrated iron oxide Fe (ON) 3 is usually called rust.
From the "Big Soviet Encyclopedia" it is known that Patina (Italian. Patina) is a film of various shades (from green to brown), formed on the surface of products from copper, bronze and brass as a result of metal corrosion under the influence of the natural environment or as a result of patination, That is, heating or processing by oxidizing agents.
Household reasons for the appearance of rust are excluded
So, since Gold Coins "Georgy Victorious" have a sample of 999, then they should neither fill up nor rust. Toothpaste with the content of fluoride connections can not spoil the coin. Just as urea. Cyanic compounds, as well as mercury, like a bromine, in ordinary life with a person do not come into contact. Traces from selections from skin sweat and sebaceous glands can be easily cleansed by organic solvents, which dissolve fat and melt inorganic compounds, but the solvents will not interact with gold.
The term "Patina" to the coins of "Georgy Victorious" is not applicable, since they consist of gold, and not copper. Herman Sterligov said this in one of the speeches: "sent [the coin" Georgy Victorious ", approx. Ed.] For examination in the" Institute of Steel and Alloys "and there, the professors explained with the smile that Patina and Gold two things are not compatible. If there is gold, then there can be no patina. If there is a patina, then it is not gold. "
In the fact that the coin consists of 999 samples gold, there is no doubt. If it were not so, it would be known about this for a long time. The fact is that the coins of "Georgy Victorious" from the very beginning of their sales in 2006 use jewelers in the production of decorations due to the lack of such VAT coins, as well as high metal breakdown in these coins.
There is no contradiction - there should be no rust, but it is. Let us return once again to the comment of the Bank of Russia's cash circulation department: "In some cases, depending on the storage conditions, spots may appear, which are oxides of metals and microscopic particles of various substances falling onto the surface of the coins. This comment is akin to the statement - Newton explained why the apple fell, but did not explain how it turned out to be on the tree. So here - the Bank of Russia explained that rust appears due to microscopic particles, but did not explain how they appear on the coin stored in a plastic capsule in the banking safe.
What really happens?
Fortunately, the world is not without good people. Representatives of the two banks sufficiently logically explained the origin of the "rust" on gold coins.
The head of operations in the financial markets "Rus-Bank" Stanislav Filippov told the following: "With regard to the defects themselves, it must be said that this problem is not new. Periodically there are separate batch of coins, on the surface of which after 2-3 years (depending on the conditions Storage) Various clouds, color changes or reflective properties manifest. All specified changes are nothing more than a defect of production, and superficial. The causes of its appearance are likely to lie in the fall of foreign chemical impurities to the surface of the stamp, possibly when it is cleaned, although More detailed information could give, probably, only the technologists of the coil.
Head of the Department of Precious Metals Bank "AK BARS" Azat Salahutdinov told the following: "Rusty" coins and ingots appear due to the presence of microscopic particles of iron on their surface, which is transferred there when contacting the iron tool during the manufacture of a coin or ingot. As a rule, this happens during stamping or rental. The rust in volume is much larger than that generated her piece of iron (about 300 times), so the fact that it is imperceptible in the form of microscopic pieces of iron becomes visible in the form of rust after storage in relatively raw room (sometimes there is enough moisture in the capsule along with air). Iron coins were transferred during the hire of a sheet, in the manufacture of blanks for coins, due to the identified cases on the mint, an investigation was conducted, which determined the origin of the defect. Now, as far as is known, this was eliminated in production, and in the ICC, the visual control of all the implemented coins is carried out. There are also such stains on the ingots, but only on stamped and, as a rule, made on worn stamps. The stamps for gold coins are covered with gold, so there can be no rust in this process, and at the affinal plant it is slightly simpler. "
How to prevent "rust" coins?
Elena Novikova recommends "Store coins in a dry place without sharp light and temperature differences. To extract, if necessary, coins from the capsule, for example, for weighing it or a detailed inspection, there are special gloves or tweezers with soft tips. In specialized numismatic stores can also be purchased Special pear for dust removal, chemicals for removal of stains, boxes and storage capsules and other accessories for working with coins. " However, as we have already found out higher, gold is very inert, and ordinary light and temperature conditions do not affect it. But the requirement for dryness of the room in the light of the above is acquired by key value.
The press service "Khanty-Mansiysk Bank" recommends "Store at the required humidity and temperature", without specifying the necessary moisture and temperature. In addition, the Bank himself acknowledged that the banking safe cell is not a place in which the humidity and temperature needed to prevent the appearance on the coins of the tracks "rust".
It is obvious that the answers of bankers affect the explicit insufficiency of knowledge gained by them in the school. Against this background, the so-called schooling reforms held by the relevant ministry under the leadership of Citizen Fursenko will lead only to even greater deterioration (although much worse) the overall level of education of the Russian population. Reforms, and, in fact, the destruction and degradation of school education should be immediately discontinued.
But we were distracted. So, if the microscopic particle of iron was on the surface of the gold coin due to production marriage, then such a coin is prevented from "rusting". The iron rusting is inevitable, because there are always pairs of water and oxygen in the air, which cause corrosion.
What to do with "rusty" coins?
Bankers are united in opinions - no reason for panic.
Azat Salahutdinov believes that "there is really nothing terrible in these stains, they are superficially, they are easily removed by simple chemicals, and practically do not affect trials."
Stanislav Filippov believes that "coins owners, on the surface of which specified defects appeared, first of all, should not be panicing and get rid of such coins at any cost. If they are purchased in a bank with a good business reputation that has long been working in the financial market, then no doubt about them There is no authenticity. In any case, the cost of such coins can not be lower than the cost of gold, which contains them. The buyer of coins may ask only a minor discount for appearance.
Do not change your preferences when choosing investment tools. Conventional people who do not have the ability to store precious metals and products from them in favorable conditions, one can recommend investing in gold by means of impersonal metallic accounts. Gold on the OMS is not available for the kidnappers and never "rusted"! ".
North-West Sberbank, when identifying "rusty" gold coins in the cash centers, they rebels and at a reduced price sells UO / WCC clients through the branch network.
Press Secretary VTB24 in the North-West Federal District Ivan Makarov offers owners of "rusty" gold coins "to handle the claim for the quality of coins, both to the seller bank and the coin manufacturer."
So, make conclusions. The problem really exists. In the production of gold coins and ingots made by stamping, there are deficiencies, due to which the smallest particles of iron appear on the surface of some coins, invisible to the naked eye. Over time, these particles of iron are corrosive and corrosion products become unarmed eyes. The defect is superficial and worsens only the appearance of the coin, without affecting its essence as capital saving means. If rust stains appeared on one or more of your coins, there is no need to try to get rid of these coins. The price difference compared to the no rust coin is 50-200 rubles or approximately 0.5-2.0% of the coin price.
Why is the "silent" bank of Russia?
By the way about the manufacturer. In the case with the "rusty" gold coins, the only thing that is not a reasonable explanation is the position of the Bank of Russia. The issuer of coins is completely indifferent to his reputation and to the reputation of his product. We found out that the "rust" on a coin is the result of a production marriage. That is, in circulation there are defective gold coins. All over the world has long been accepted that the defective goods change free of charge at the expense of the manufacturer. And the Bank of Russia does not respond to the situation in any way. Already at least six months. Not only does it, according to Stanislav Filippov, the Bank of Russia back does not buy a coin, and Russian banks have no opportunity to replace defective coins. So after all, the issues of reverse redemption by credit organizations of coins in the population by the Bank of Russia are not regulated. So reported in the Department of Cash Cash Regulator. And why does the bank of Russia do not replace its defective coins? And when will he start doing it? Or only the court decision on the case of the protection of consumer rights is able to force the Bank of Russia to fulfill their duties properly?
