How to identify the authenticity of silver coins in Qing Dynasty

1, listen to the sound. Is to distinguish by the sound of silver dollars colliding with each other. Gently press one fingertip upward at the center of the silver dollar, and tap the edge of the silver dollar with another silver dollar to make a crisp and soft sound. This is the real silver dollar. If the voice is sharp and high, with a copper sound, it is a low-component fake silver dollar containing a lot of copper.

If the voice is low and hoarse and the periphery is inconsistent, it is a fake silver dollar dug by the foreskin. Generally, the sound of fake silver dollars is mostly short and dull.

2. Look at the appearance. Look at the shape and structure, pay attention to whether the color, pattern, pattern, size and thickness of the silver dollar are normal, whether there are any abnormal phenomena such as pickling, filing, edging and digging, and whether the silver dollar is printed privately. Generally speaking, the diameter of fake silver dollar is slightly smaller than that of real silver dollar. As long as it is compared with the real silver dollar with the same volume, it can distinguish the authenticity.

3. Check the edge teeth. Because the real silver dollar is a mechanism version, its side teeth are detailed and symmetrical, and the rules are even; The side teeth of counterfeit money are rough and uneven, and some have traces of local file repair. As long as you are careful, it is easy to distinguish with the naked eye. For example, there is a fine tooth in the two coarse teeth of the real "Yuan Datou" lateral tooth, while the fine tooth of the fake "Yuan Datou" is ambiguous.

Step 4 weigh. The standard weight of silver dollar should be 26.5g, and the color is 88%. After wearing a normal silver dollar in circulation, its weight should also reach 25.8 grams. Anything that weighs less than 25.8 grams and has a fineness of less than 84% is either washing dishes, filing edges, wrapping, digging silver dollars, or counterfeit money.

5. Acidity test. Drop a drop of nitric acid on the silver dollar. Look at these bubbles, 7 green, 8 black and 95 white.
