@yintercept: I fear that the amount of fake silver and gold is likely to increase with time as people who encounter coins try to pass it off so that the forgeries become problems for others. I prefer to buy coins locally because it is easier to seek legal recourse for local trades. good luck sorting out this problem. !WINE
@kerrislravenhill: I've handled a lot of silver over the last eleven years it would feel obvious. If this was the first few sales of a silver bar, perhaps. If the Seller have sold many silver products, then I would be suspicious. However, you should return it for a refund as this product was not what you have purchased. Does Facebook have a Seller Ratings or Service feedback policy? I have never bought or sold anything on FB.
