j_stat New Member United States 3 Posts	Posted 07/12/2024 8:47 pm I bought this coin about a year ago and didn't know what PVC damage was on coins. I've since learned a bit and have learned that green spots on silver is not a great sign. Would you all think this is PVC damage? I'm new to collecting and if there is a way to mitigate the spread or any pitting I'd love to do that. I've heard that acetone can be used sometimes, but I really don't want to devalue this coin and I don't want to remove any of the luster from it. It's an amazing coin, but I really don't want to damage it in anyway. It's in an air tite case now, so I can't really tell if its sticky or not. I just know it appears to be greenish in shade. Someone suggested it might be bronze damage, but I'm not sure how I would have acquired that on a silver coin. Report this Post to the Staff

j_stat New Member United States 3 Posts	Posted 07/12/2024 9:08 pm Thanks for the reply! Will soaking it in acetone do anything to the luster on the coin? Or will it remain? I've seen individuals use cue tips & acetone to target certain areas on coins, but I feel like this method could result in micro scratches. Report this Post to the Staff
Dearborn Moderator United States 94932 Posts	Posted 07/12/2024 11:39 pm to CCF! yes, a nice long soak in acetone - the good stuff from a hardware store NOT fingernail remover junk - that will ruin the coin. Then a rinse in fresh acetone after the soak to wash off any residue and then a fresh water Rinse. Do NOT rub the coin. Collecting since 1972. Learning from then on "Tell me and I forget.

John1 Moderator United States 56855 Posts	Posted 07/13/2024 04:38 am Is the holder it is in an Air-Tite brand holder? After treating it with 100% pure acetone do not put it back in that holder. Buy a new Air-Tite brand capsule. John1 Report this Post to the Staff

Sharks Pillar of the Community Canada 1761 Posts	Posted 07/14/2024 1:07 pm With all the points above. Acetone will not hurt lustre of coin, just don't rub it in. @j_stat Report this Post to the Staff
j_stat New Member United States 3 Posts	Posted 07/14/2024 8:38 pm Thanks for all of the advice from everyone! I'll be soaking it in acetone and seeing if that blue/green gunk will come off of it and ordering a new holder for it. I'm still relatively new to the coin collecting hobby, so thanks for being a supportive community! Report this Post to the Staff
Sap Moderator Australia 16809 Posts	Posted 07/14/2024 10:05 pm Silver - especially .900 fine US coinage silver - does not turn green easily. "PVC goo" is one explanation, but the other is "corrosion", caused by some nasty corrosive substance getting spilled on it. The way this looks like a "splatter pattern" makes me concerned this is actually something noxious having been spilled on the coin long ago. If acetone doesn't do the trick, then a TPG conservation submission might be in order. It's frankly too nice (and too valuable) to experiment with. Don't say "infinitely" when you mean "very"; otherwise, you'll have no word left when you want to talk about something really infinite. - C. S. Lewis Report this Post to the Staff
