<p>[QUOTE="Conder101, post: 427128, member: 66"]Proofs may possibly tone faster because I believe they go through a final cleaning step after striking that the Unc coins do not. This leaves the metal bare and exposed to the elements while the Unc coins may still have a thin oil film on their surfaces which helps to protect them from gases and water vapor.[/QUOTE]</p><p><br /></p>
