Unfortunately unless you buy one and can prove it is counterfeit, i.e. your walking liberty silver dollar, you are only assuming they are counterfeit, although they probably are. I also purchased a counterfeit silver eagle at about book price from a US seller. In my case the coin size, weight and stamping were correct but when I tested it the metal content was off. Opened a NAD chargeback, since eBay process would have required a return of the item which violates federal law, but CC company issued credit in less than 30 days.
I am in the Washington D.C. area and have taken these counterfeit coins to the Bureau of Engraving and Printing and even the Treasure department will do little to try and combat the proliferation. They don't have the resources and there is little they can do to stop China from counterfeiting anything. They did however take down the sellers information and took possession of the counterfeit coins I had which was fine by me I had been refunded for my purchase.
