How do you identify real gold coins? How gold coins are authentic

There are three main ones, the first must be purchased from the authorized regular dealers designated by the China Gold Coin Corporation; Second, it must be issued by the People's Bank of China and manufactured by the mints under the Banknote Mint Corporation to be considered real gold coins; Third, what can be found in the People's Bank of China ** and Chinese gold coins **, the size, weight, pattern and quality can be unified is the real gold coin.

To sum up, the current counterfeiting of commemorative coins in the Guangzhou market is mainly the following two types: One is to charge coins with stamps. In China, only the People's Bank of China has the legal authority to issue currency, can issue products called "coins", China Gold Coin Corporation is the only general distribution unit of China's *** commemorative coins, in addition, any institution issued round *** products can only be called "chapter" or "plate", and can not be said to be gold coins and silver coins.

Second, the "gold content" is insignificant. Gold coins issued by the People's Bank of China have a range limit on the "gold content" (that is, the percentage of **value in the issuance), generally 15% to 60%, and a few investment gold coins such as panda gold coins can even reach more than 90%. In the current medal market, some commercial organizations have issued some alloy gold medals, which only coat a thin layer on the alloy products made of copper and iron.

I have collected some so-called gold coins with a gold content of less than 1%, as a reference for counterfeit and inferior coins, and its 1 ounce weight product, the value of ** material is equivalent to less than 60 yuan, but it was sold by merchants for thousands of yuan. There are many ways to identify "real gold coins", in simple terms, there are three ways: First, try to buy from the authorized dealers of China Gold Coin Corporation marked with the trademark plaque of "China Gold Coins".

Second, we should pay attention to the issuance, minting and distribution units of products, and only those issued by the People's Bank of China and distributed by the China Gold Coin Corporation are commemorative coins. Third, the People's Bank of China ** and the China Gold Coin Network have the corresponding specifications of gold coins issued in each year, and citizens can generally identify whether the products sold are genuine according to the standard size and size of the volume and weight of such official ** commemorative coins.

The best thing is to ask an expert to get it done.

The certificate is not RMB paper The weight of the coin is also very easy to distinguish I have been in contact with it before and said that it is a gold coin There is no weight at all in the handle It must be fake Some will also take real gold and silver to counterfeit But look at the minting process to know that the mint will be much more delicate and look at the gear and look at the mirror The authenticity will be different.

The basic principle is that the denomination issued by the People's Bank of China is the currency, otherwise it is a medal.

Also, please buy a catalogue of Chinese gold and silver coins, most of which are not on the catalogue are not real.

To distinguish the authenticity of gold and silver coins, find Beijing Zhongyi Tuopu.

There are three main ones, the first must be purchased from the authorized regular dealers designated by the China Gold Coin Corporation; Second, it must be issued by the People's Bank of China and manufactured by the mints under the Banknote Mint Corporation to be considered real gold coins; Third, what can be found in the People's Bank of China ** and Chinese gold coins **, the size, weight, pattern and quality can be unified is the real gold coin.

Three tricks for gold and silver coin identification.

At present, there are too many counterfeit coins on the market, especially the early gold and silver coins in China. A quick and easy way to identify gold and silver coins is a must-have for coin collectors. After research and verification, the author has summed up a simple identification method, this method is only suitable for ordinary gold and silver coins, especially gold and silver coins in the world's coins, if it is a rare coin, then it is recommended that you still find relevant experts or special identification units for identification.

The simple identification method is divided into two steps: one is to check the data; The second is actual testing.

There are a lot of books and materials about gold and silver coins, such as the "World Coin Standard Catalogue" published by Claus Publishing House in the United States and the "Chinese Silver Coin Identification and Trading" published by China's Knowledge Publishing House. By checking the information, you will have a preliminary understanding of the coin.

The actual inspection is "one look, two scales, three measurements", and at the same time must have three tools, namely a magnifying glass, a balance and a vernier caliper. The so-called "look" is to look at the appearance of the coin, take a magnifying glass to carefully look at the surface and pattern of the coin, to see whether there is rough sand holes, etc., the content of "looking": one is to identify whether it is a gold coin or a silver coin, a copper-nickel coin or a brass coin; The second is to identify whether the shape and pattern of this coin are the same as those introduced in the information.

You can get an idea of the situation by "taking a look". People who often come into contact with gold and silver coins can tell what kind of coin they are by "looking at it".

The second is to weigh the weight. Gold and silver coins and copper-nickel coins are not the same in terms of material density. White gold (platinum) has a relative density of 21 48 and is the heaviest; ** has a relative density of 19 26, followed by 19 26; The relative density of silver is 10 29, again; Copper and nickel have a relative density of 8 90 and are the lightest.

The best way to avoid buying gold-plated silver coins or gold-plated copper-nickel coins is to weigh them. We can weigh it on a balance to see if it is the same as described in the material. If you buy a gold coin, take it to a gold store on the street, ask them to weigh it with an electronic scale, and then determine the gold content.

If the weight is the same as the one on the scale, or if it is slightly lower due to wear and tear, it is a real gold coin.

Third, you can use vernier calipers to measure the diameter to see if the diameter of the coin is the same as on the data, and you can further identify it. If the design, text, material, weight, and diameter are the same as on the data, the coin should be genuine.

1) Look at the color: **The higher the purity of the jewelry, the darker the color.

3) Look at the hardness: pure gold is soft and has low hardness.

4) Listen to the sound: real gold with a fineness of more than 99 is thrown on the hard ground, which will make a horn sound, with no rhyme and no elasticity.

5) Burn with fire: burn the jewelry to be identified with fire (do not melt and deform the jewelry), observe the color change after cooling, if the surface is still the original ** color is pure gold; If the color is darkened or darkened to varying degrees, it is not pure gold. Generally, the lower the fineness, the stronger the color, and all of them turn black, indicating that it is fake gold jewelry.

6) Look at the mark: domestic ** jewelry is purified and prepared according to international standards, and the resistance and cover are marked with a killing mark, such as "24K" marked "foot red" or "pure gold"; The shed beam is 18K gold, marked with the word "18K", and the fineness is lower than LOK, according to the regulations, it cannot be marked with K gold seal. At present, lawbreakers in the society often make fake brands, imitation stamps, and use rare gold, Asian gold, and even brass to pass off as real gold, so the identification of ** jewelry should be based on the sample for comprehensive judgment to determine the authenticity and fineness.

With fire, real gold is not afraid of fire.

(1) Observe the quality of the paper. Real RMB paper is tough and resistant to folding, while fake RMB paper usually lacks toughness, folding several times in a row on the same line, and the face of the ticket will break with a slight pull.

2) Observe colors and patterns. Since everyone is often in contact with the RMB, the colors and patterns are more impressive. When observing colors and patterns, the main thing is to see if the edges are clear. The edges of the colors and patterns of the real RMB are clear, and the edges of the colors and patterns of the fake RMB are usually blurred.

3) Rub test. Although the color and pattern of the renminbi with a large denomination are clear, the patterns and patterns printed with dark ink will still leave traces of that color on the white paper after being rubbed the white paper, but the face of the ticket is not blurred. This is usually not the case with fake yuan.

4) Watermark. If you look at the renminbi against the light, you can see the usual invisible portraits, Tiananmen Square, and other patterns, which are usually not the case with fake renminbi.

5) Touch. The real renminbi is printed with embossing, and the face of the ticket (especially the new one) feels concave and convex. Fake renminbi is usually printed with photographic plates and has a smooth surface.

6) Insurance lines and points. In recent years, there are metal wires in the new version of large-denomination RMB paper, or there are several black dots on the lower right of the front side, the black dots are not printed like other patterns, and there is obviously a certain thickness.

See: It is to carefully observe whether the watermark of the banknote printing pattern is clear and whether the layers are distinct. The portraits of the characters on the genuine coins are natural, realistic, three-dimensional, and the watermark pattern is clear when viewed into the light.

The portrait of the counterfeit currency is bland, the demeanor is dull, there is no three-dimensional sense, the watermark is blurred and no layer, the ground lines are composed of dotted lines, the microtext is not clear, and there is no photo-changing ink effect. Hand touch: It is to judge the authenticity by feel.

Coupons of more than two yuan are printed in gravure, and the gravure parts are touched by hand, such as the line name, number, Braille dots, etc., which have obvious concave and convex feelings, while counterfeit money is generally smooth and has no concave and convex feeling. Comparison: It is to compare genuine and fake coins together.

Distinguish from the color of the ink, the size of the banknote, etc. If you find a suspicious coin, you can find out the difference and identify its authenticity as long as you carefully compare it. Listen:

That is, to listen to its sound with your ears to judge the authenticity. Grab the two ends of the banknote with your hands and stretch and pull or grab one end to flick or shake, because the RMB is made of banknote special paper, the paper is tough, the stiffness is good, and the sound is crisp when listening carefully, while the counterfeit money is printed on ordinary commercial paper, the paper is poor, and the sound is muddy when shaking. Instrument testing:

It is to use a counterfeit identification instrument or magnifying glass to identify it. Generally, counterfeit coins will have a white fluorescence reaction when exposed to ultraviolet light, while genuine coins do not react abnormally. Use a magnifying glass of more than 10 times to observe the pattern lines, if the portrait is dull, the layers are not clear, the ground lines are intermittent or there are overlapping broken lines, it is a counterfeit.

Relevant people in the financial sector reminded that in daily life, people can adopt the method of "looking, touching, listening, and testing" to identify counterfeit money. Take a look at the watermark. If you are more than 10 yuan, you can see a watermark such as a portrait at the watermark window.

Counterfeit watermarks are usually stamped with light-colored ink on the front or back of the banknote, or a white paste is applied to the interlayer, and then the watermark impression is pressed on top. The watermark of a genuine coin is vivid and expressive, and has a strong sense of three-dimensionality, while the watermark of a counterfeit coin lacks a three-dimensional sense and is mostly composed of lines. Second, feel the bumps.

The upper forehead above 5 yuan is intaglio printing, the lines form an ink channel that protrudes from the paper, and there is a more obvious concave and convex feeling in the braille dots, the words "People's Bank of China", and the fifth set of RMB portraits. Counterfeit coins are generally printed on offset plates, which are smooth and have no uneven feel. Three listen to the sound.

The renminbi paper is a special paper, strong and crisp, and the newer banknotes make a crisp sound when you flick your fingers. The paper of counterfeit money is soft and thin, and the sound is muffled, and it cannot withstand crumbling. Quadruple fluorescence.

The RMB paper is not fluorescently bleached, and there is no fluorescent reflection under fluorescent light, and the paper is dark. Most of the counterfeit paper is bleached, and there is a clear fluorescent reflection under fluorescent light, and the paper is white and shiny. There are one or two fluorescent characters in the RMB, which are pale yellow, and the fluorescent characters of the fake RMB are not shiny and colored, and they are miserable white.

There are clever ways to distinguish the authenticity of the RMB, learn these tricks, and you will never be afraid of receiving fake money.

First of all, take the money in both hands and put it in front of you, facing the sun or a big light bulb that is on, and see if you can vaguely see Grandpa Mao's dignity, if not, it is fake If there is a second step. In the second step, you can dip the thumb and index finger of one hand in saliva or water, clamp the banknote and rub it repeatedly. A few minutes?

No, 10 seconds is fine. Don't push too hard. And if the banknotes are okay, then 80% of them are real.

If you still don't believe me, move on to the third step. The third step is to take the money and passbook and run to the bank to --- deposit If you can pass it smoothly Congratulations, it's real money.

How to verify the authenticity of a silver coin:

The first method is "knock".

Take two silver coins, hold the center of one silver coin with the fingertips of both hands, and slowly move closer, when the two silver coins coincide about a quarter of the position, so that the two silver coins gently knock each other's edges, the sound of the genuine coin is crisp, and the sound of the counterfeit coin sounds wooden.

The second method is to "blow".

Gently pinch the center of the silver dollar with your index finger and thumb, blow the vertical edge of the silver dollar violently, and quickly put it to your ear to listen. Most of the current forgers borrow computer plates, and pass off as silver with alloy materials, and their colors, texts and pictures can be almost confused, but in the end, because they are not silver, their pronunciation is sharp and long, and insiders will know the authenticity as soon as they distinguish it.

The third method is "weighing".

The genuine coin is generally full of weight, and the loss of circulation is also about 26 grams, and its color is moist and soft white, the timbre is soft and long, and the text and pictures are accurate, and the pulp is natural; Counterfeit coins are generally underweight, or overweight due to overweight, and grayish in color.
