The salts on your hands from perspiration leave the finger prints the coin. You might not see them today, but in a few years they will be seen. Then it is too late as the metal has been affected. So if you see a finger print on the coin...PASS. They can not be removed without ruining the finish. Water on cents will turn them green. So if you was a coin, make sure it is total dry before putting into a flip or 2X2.
