Sun Yat sen s founding commemorative coin is wrong, how to distinguish the authenticity of Sun Yat s

Friend, I will introduce the method of authenticity and falsification.

The first method is to "knock", take two silver coins, hold the center of a 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 real coin is generally full weight, and the circulation loss is also about 26 grams, its color is moist and soft white, the timbre is soft and long, the text is accurate, and the pulp is natural; Counterfeit coins are generally underweight, or overweight due to overweight, and grayish in color.

Hide "without leaking.

I am welcome to join the group.

Summary. Hello, identification method: silver, that is, the metallic color of the silver round.

The silver white of the real silver round is moisturized, the luster is soft, and the color reveals a natural color. Although the fake silver round is made of **, but due to the formula of the metal composition, its silver color is different from the old silver dollar, generally white with blue, strong luster, the color is stiff and dazzling, in the jargon: it is with "thief light".

The teeth of the silver round have two major functions: anti-counterfeiting and anti-theft of metal. In the identification of silver rounds, the side teeth are a very important link.

A common Achilles' heel of modern high-imitation silver circles is that the side teeth cannot pass.
