You must be a coin dealer or ignorat? Which one is it? I have done my research and if you have the means you can find out just about anything. I have the evidence that this happens, and has happened to me on several occassions. You really think I would just make something like this up? Really? Yes the certificate number changes, but if you can afford to hire some one to research on your behalf, it may open your eyes. How have you benefited from the Coin Dealer Owned Grading Service's?
