<p>[QUOTE=&quot;WingedLiberty, post: 1950273, member: 26030&quot;]No idea how or why this happens, but I think it&#039;s cool looking when it does.&nbsp; I always keep my eye out for interesting looking toners. PCGS has graded many of the ones I&#039;ve found as problem free (or at least market acceptable). Most I have cracked out myself in apparently unopened OGP Proof Sets. I do submit all of them to PCGS using the Secure Plus Service so they could be sniffed for illegal chemicals, which is the best I can do as a novice collector to weed out treated coins. Remember these dollar coins are mostly copper, which I think is the most reactive metal used in coins.&nbsp; I haven&#039;t found any toners in this series past the 2010 issue, so it appears to take at least 4 years to develop any color (although if you look closely at my set above, you will see the 2011 and 2012 issue is mellowing pretty nicely to a golden yellow -- the 2013 and 2014 issue is mostly white (all those photos were taken this year). </p><p><br /></p><p><img src="https://mindstar.com/cointalk_photos/Pres_Toned_Revs.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="https://mindstar.com/cointalk_photos/ZacharyTaylor_SlabO2.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="https://mindstar.com/cointalk_photos/TVBlack_2009-S_Taylor.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" /></p><p><img src="https://mindstar.com/cointalk_photos/TVBlack_2008-S_VanBuren.jpg" class="bbCodeImage wysiwygImage" alt="" unselectable="on" />[/QUOTE]</p><p><br /></p>
