[QUOTE="princeofwaldo, post: 1251130, member: 24091"]That's EXACTLY the first thought that went through my mind. Reverse of an 1652-A Louis D' Or pictured. The "haymarks" or more accurately streaking is much more evident with coin in hand, but you can still see a significant mark at 7:00 on the reverse about 3mm up from the rim. Also a scattering of marks at 1:00 in the legend. Only one thing kind of troubling about the conclusion. Tin has a melting point less than half of either gold or silver. I suppose impurities in the tin amalgam could raise the melting point, but realistically, I can't imagine a scenario where tin would not go into solution at temperatures greater than twice its melting point.
