Is this a result of a PVC holder ? How can I remove it beside Acetone or Xylene ? Or should I leave it be ?
+1...used correctly (<10 seconds) and clearly rinsing the coin with distilled water and patting (NOT RUBBING) dry with a soft, lint-free cloth (NOT A PAPER TOWEL) works wonders for silver coins. I would NOT recommend this for gold or copper, however.
If the PVC residue on the surface of the coin is properly conserved/removed soon enough, the coin may escape with minimal damage that is not visible to the naked eye. If the green PVC residue is left on the coin for a long time, it will start eating into the surface of the coin. When I see PVC, I first try a Q-tip and 100% acetone. If that doesn't work, out comes the eZest. Just one man's opinion.
If there is a local numismatist in your area ask for advice on cleaning before you attempt it. Most attempts to clean a newer coin will depreciate the coin's value, be very careful. Good luck
Acetone is your best bet. It will remove any PVC from the coin. Make sure to soak it in a covered dish (glass works great) Let it soak for a period of time. Then transfer it to a second clean fresh container of Acetone for a final bath. Swirl the coin in the Acetone, but don't rub it. Acetone can be purchased from many hardware stores. Look for 100% Acetone. It will air dry when removed from a bath in just a few moments.
