Fake silver coins are often made of base metals such as copper, brass, aluminum, or other alloys. They may also be plated with a thin layer of silver to give them the appearance of being genuine. In some cases, fake silver coins may even contain traces of real silver but in amounts too small to be valuable.
Fake silver coins can be identified by various tests such as the ping test, magnetic slide test, ice test, acid test, or sometimes with simply a magnifying glass.
