Copper castings. In the market, we sometimes see copper silver coins. The silver ring is an imitation, mainly made of brass, and there is a silver film around it to confuse people. This kind of imitation silver ring is also relatively easy to identify, first of all, it can be preliminarily judged from the sound. Because its main material is copper, because of the inherent characteristics of copper metal, it will make a particularly sharp and harsh sound when knocking. Secondly, if the silver ring is worn enough, its edge will emit a little yellow light.

Made of lead. Silver cakes made of lead can also be covered with silver. Lead has poor heat resistance. This material is afraid of heat. If the silver circle is baked in the fire, lead may run out of it.

Sandwiched silver round. Imitation usually has a thick silver coating on the front and back, but in order to save silver, it also includes a mixture of other metals, such as iron or copper.

This situation is difficult to distinguish, because its silver is thick, and it is difficult to tell the difference even if it is worn. But judging from the sound it makes, it still has a big problem. Its voice is low, unpleasant and not harsh, and it sounds a little dull compared with the sound made by the real silver circle. In addition, the weight of the filled silver ring is slightly lighter than that of the real silver ring, which generally cannot meet the weight standard of the real silver ring.

Carve a silver ring instead. Carved silver coins are also emerging in the market, which is difficult to distinguish. Usually we make a fuss about rare silver coins.

For example, take an ordinary three-year-old genuine big head, and then add an English name of George Lu to the right of the original picture to make it look like a signed version. The value of the signature version is obvious to all, dozens of times higher than that of the ordinary three years. These are all means to obtain high illegitimate profits.

Judging from the pressure on the side teeth and the whole coin surface, the details of such a silver ring are still quite realistic, and there is almost no problem. After all, it is authentic, and the voice will not show flaws. Only by carefully observing every trace of the font and slowly comparing it can we see its tricks.

Real silver counterfeit money. This kind of imitation uses enough silver as raw material, imitates it according to the real silver circle, and then manually processes it. It is a kind of counterfeit money that easily confuses Tibetan friends.

In the face of such counterfeit money, you can't tell it completely by listening to the sound, because it is made of pure silver. But after all, it's not like a real silver circle. It's printed by a professional mint. If you look closely with a magnifying glass, you will find that there are tiny trachoma in some places on the surface of the coin, and the overall pattern is not three-dimensional.

How to identify the authenticity of a silver dollar?

1. Judging the authenticity of a silver dollar mainly depends on the color. The longer the year, the whiter the color, not too dazzling. The silver of counterfeit money will be brighter, smoother and more wear-resistant.

2. The silver dollar can also tell the truth from the sound. Really, silver coins are peaceful, crisp and echoing. When a silver dollar knocks on the edge of another silver dollar, it will make a crisp sound. Counterfeit money, on the other hand, makes a higher and sharper sound and sounds clearer.

Due to the long-term circulation of silver coins, there is usually a layer of patina on the surface. The patina is a uniform, thin and stable oxide film with oily and sweaty deposits and rich colors. However, the fake is not wrapped, and even if it is, it is a single dark color.
