<p>[QUOTE="ksparrow, post: 432006, member: 7638"]Does 'gate mark'= spot where sprue was broken off on a cast copy? If so I would expect that to be right on the edge, where it would be filed off. (correct me please if I misunderstood) I think this is a copy using a transfer technique to make a false die, which was then used to stamp the coin out of a disc of soft heated metal. Since the transfer material shrinks to some extent, in order to get the coin the right diameter they have to make the fake die wider, so the rims get fatter. I am not sure exactly how they do this, but often the rims are grainy and full of pits. Tiny holes, with a small blob of metal in them, are very common in the dentils of transfer die fakes, and one of the easiest ways to out these forgeries-- but you have to be looking at nice big photos or else have it in hand with at least a 10x loupe-- the usual ebay photos are too small to see them, one reason so many are sold. Another technique is to apply the rim separately to the stamped out center of the coin, but you can usually spot a seam when this is done, or it will be coming apart.[/QUOTE]</p><p><br /></p>
