China Neodymium And Ferrite Magnets Manufacturer & Supplier 
How do I know if the silver coin I'm holding is real or fake? What are the ways? Today, I will take you to use a strong magnet (silver coin authenticator) to judge, you can easily rule out imitation silver coins.
The picture below shows the powerful neodymium magnets used for silver coin authentication, some of which are also wrapped in stainless steel.
Steps to use to authenticate a silver coin with a magnet;
1, Place the magnet flat on top of the silver coin.
2, Lift the magnet quickly in an oblique upward direction
Authentication results; Genuine silver coins contain 89% silver and 11% copper metal, silver dollars that can be turned over have normal silver content. Can move but can not flip the silver dollar content is not normal. Motionless and firmly sucked is a fake silver dollar. Identification also needs to be combined with the edge teeth, weight, sounds, size and other aspects.
Working Principle
Because the composition of the silver circle is not pure silver, it contains a certain amount of copper and iron and other components, and the appearance of modern high imitation silver circle can be fake, but the ratio of raw materials can not reach the degree of real coins. Silver circle identification device is to seize this feature as a breakthrough, so that false silver circle has no hiding. The identification principle is to use the identification device can absorb iron but can not absorb silver characteristics, to identify the proportion of silver circle components, so as to achieve the purpose of identifying true and false silver circle.
Note: The magnetic silver coin appraiser must choose the right one, not just buy a magnet on the market to test the effect, magnetic low, really can not turn over. Magnetism is too high, ordinary high-fashion also turn over, the loss is not worth it.
Friendly reminder, the instrument is not omnipotent, can not turn is basically fake, but can turn is not necessarily the old silver coins, there may be high-tech modern high imitation coins, collectors should learn more silver dollar edge teeth, word shape, wrapping, etc. Knowledge, to maximize the avoidance of unnecessary losses in the field of collection.
