<p>[QUOTE=&quot;desertgem, post: 3621133, member: 15199&quot;]Hate to spoil the fun, but there are no oil glands on the fingertips. Fingerprints are caused by the salts in sweat from the sudoriferous glands on the fingertips, corroding the metal. If you rinse every coin with acetone or distilled water and dry before putting it away, no finger prints. If you are sweating in a coin show, possible fingerprints weeks later on bare coins. Once the metal is corroded&nbsp; , acetone or no organic solvent will remove it. A dip should only be considered if it was silver, not copper. I do not think anything would remove the print shown on the cent. I was talking about the silver coin in post #1</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
