One is size (including thickness). Some shoddy fake silver coins don't even pass the size. For such a low-level fake. Ordinary couples are not difficult to tell.
The second is color. Like other collections, the forgery of texture is an extremely difficult link, because even if the forger knows the main components of the imitation object, he can't find out the content of trace elements, let alone how to add and cast these trace elements. These trace elements often determine the appearance of silver coins, so that fakes reveal clues. Generally speaking, ordinary fake silver towels are slightly yellow in silver, while some high-end fake silver is slightly white.
The third is weight. The size is the same, but the weight is not necessarily the same, so we use scales to distinguish authenticity. Yuan Shikai's head is a one-dollar silver coin, which generally contains 89% silver and other metals 1 1%, weighing 26.8 grams, while counterfeit banknotes generally weigh less than 25 grams.
The fourth is timbre. Due to the texture, silver coins will make different sounds when struck, which provides convenience for the "sound recognizer". Under normal circumstances, the sound made by the knock of genuine goods is mellow and pleasant, and it is long and transparent, while the sound of fake goods is short and stuffy, and some are sharp and harsh.
The fifth is the casting process. The traditional machine casting of silver coins is made by stamping technology. If counterfeiters use sand casting or other casting methods, they will leave clues, either uneven shading or sand casting particles. With a magnifying glass, it is easy to find some problems. The imitation gold and silver coins, some of which are made of high-tech or old molds, are highly simulated, and friends who often collect them are cheated by this kind of silver coins.
The sixth is the text mode. Mainly depends on whether there is post-casting, whether there is a change in lettering. The biggest feature of post-casting and post-engraving is that forgers are all shoddy. Therefore, focusing on the difference between common products and treasures is a good way to crack this counterfeiting method.
The seventh is the tooth edge. Under normal circumstances, the edges of real teeth are clear, neat and even (except some Jilin silver coins). Dentures are disordered and chaotic.
Eight is the overall effect. Observing the overall effect is a further examination after combining various factors. If the above items focus on showing their shapes, then this one is to seek their gods. Strictly speaking, the vast majority of fakes are nothing more than modeling. In the eyes of real experts, they can only be classified.
Of course, the above experience in identifying counterfeit goods is only some basic identification theories, and the practical operation ability can only be obtained in practice. Many things involving the essence of "eyesight" can only be understood but not expressed.
