[QUOTE="Cherd, post: 8520536, member: 24754"]There's a reason that I don't do my own coin attributions :) The bust didn't look like any Pius that I'd ever seen, but the name is plainly spelled out on the coin. Guess that's not very informative when they all perpetually recycled the same names! I did a quick search on PVC damaged silver coins, and the photos suggest to me that this is a good candidate for your issues. Maybe some residue was left on the coin? Or the problematic gases managed to penetrate some micro-porosity? The discoloration seems to be restricted to only the high points on the coin, so that further supports this theory IMO. Seems to me that, if this type of thing was on the surface, then the acetone would have removed it. Hopefully that did the trick ;)[/QUOTE]
