My son-in-law gave me a 1900 silver dollar today and I examined it very close and he said to put a magnet next to it and the coin stuck to it. His brother had given him a few of these coins to him as he had got them from storage locker auction. I was told that it is a Chinese counterfeit silver dollar and if you didn't use a magnet or look at it with jewelers lope you would never know that it wasn't real. Beware out there.
