dacp New Member United States 20 Posts	Posted 08/22/2021 2:52 pm I have a 1908 Saint-Gaudens double eagle. When I first got it I was not familiar with coins so I did not hold it by the edge. I touched and rubbed it all over with my fingers. I found it strange that I did not leave any fingerprints on it. I learned that you should not clean old coins so I have not used acetone on it. Should I use acetone on it? I already touched it so I'm afraid in the future some discoloration/fingerprints might appear because of that. Should I use acetone on all coins before putting them in Air-Tites to get rid of any unseen contaminants? Report this Post to the Staff

Giving coins an Acetone treatment is not considered cleaning them . It will not harm your coins . Report this Post to the Staff

Fortunately gold is pretty inert and will not likely develop fingerprint marks. Report this Post to the Staff

Just make perfectly sure that you keep acetone well away from coin capsules or slabs. Even a tiny droplet of acetone on a coin capsule or a slab will do damage. Acetone is a strong solvent of the type acrylic or polystyrene plastic from which capsules and slabs are made. Used very carefully, I have even used tiny droplets of acetone to permanently seal a coin capsule. The capsule will need to be broken to get the coin out.
