If you live in the NY area be aware. I was in the lcs last week when the owner told me something. Some guy walked in with a stack of Trade Silver dollars and wanted to sell all of them. At the time he was in back of the store and his wife was dealing with the seller. Being less experienced in coins than the owner she was ready to buy all the coins, that is until she took one and asked her husband. When he looked at the one coin he knew right away it was a fake. Thats when he looked through the stack and found out they were all fakes. The seller still wanted to sell them knowing they were fakes and of course the owner turned him away. This seller may try to pass these off to other people most likely in the NY area.
I assume by 'Trade Silver Dollar' you mean 'Trade Dollar'. If so, yes, there are TONS and TONS of fake Trade Dollars out there.
