Removing smudges/fingerprints

Postby philadelphiafan » Mon Mar 26, 2012 5:31 pm

I was wondering if there are any ways to remove smudges/smears/fingerprints of silver bullion coins.

If the prints haven't stained or toned the coin, acetone would remove the prints. If the print has toned, or stained the coin, a thiourea "dip" would work. Be sure to test on a coin that doesn't have any numismatic value first.
