<p>[QUOTE="springfld.arsenal, post: 342944, member: 54"]I know zip about coins but I’d think a silver coin minted in 1783 would have some patina. Coin on left obviously lacks it. If real, maybe it was chemically cleaned and left in a corrosive fluid too long, removing enough metal to both leave pits and remove the weight difference noted. Is cleaning old coins a common practice?[/QUOTE]</p><p><br /></p>
