How to identify the authenticity of seven-cent silver coins produced in Guangdong

It is difficult to identify silver coins. Let's talk about three tricks first:

One is observation. Silver coins are machine-made coins with smooth surfaces and detailed images. If the surface is rough, the image is blurred and the side teeth are irregular, it is a sand table silver coin.

The second is the mirror image method. Observing with a high magnification magnifying glass, the image of real money has charm, high density, smooth surface, or green rust in the pit; If there are tiny trachoma, the image has no charm, or the old color has no patina, it is imitation sand silver coin; If there are knife marks on the font, it is a revised silver coin.

The third is the gravimetric method. Weighed with a balance, the real money weighs about 26.6 grams; Fake silver coins of the same size are generally 20-22g, that is, silver-plated or sand-plated silver coins.

There are also specific marks on the edges of teeth. The market price of Guangxu in Guangdong Province is about 1500.
