<p>[QUOTE=&quot;CamaroDMD, post: 1260692, member: 5233&quot;]Silver coins develop an oxidation layer on their surface as they age.&nbsp; Depending on how they are stored determines how thick this oxide layer is.&nbsp; Sometimes it can be very colorful and actually add to the beauty of the coin and other times it can be very ugly and make the coin look bad.&nbsp; It can even be damaging to the coin if enough is present.&nbsp; As a result, chemical dips have been developed...coins are dipped in these solutions to remove the toning.&nbsp; However, the toning is integrated into the molecular structure of the surface of the coin.&nbsp; So, the dipping actually removes a tiny bit of the surface.&nbsp; If this is done properly, the coin looks new and undamaged.&nbsp; If the coin is over dipped, it begins to lose it&#039;s luster and starts to have a dull appearance.&nbsp; I don&#039;t know if you saw it...but I made the first response in this thread and my initial thought about this coin was it had been over dipped.[/QUOTE]</p><p><br /></p>
