<p>[QUOTE=&quot;Slu, post: 210646, member: 8338&quot;]While I agree that a couple of those don&#039;t look very natural, I would think PCGS and NGC (as you say they are all slabbed by) would have picked them out as fakes. Here are some signs of fake toning:</p><p><br /></p><p>From the video &quot;How to Tell Artificial Toning on Coins&quot;</p><p><br /></p><p>- Circular toning spots resulting from the beading of the toning liquid that was used.</p><p>- Colors that blend together out of sequence. With naturally toned coins, the progression is yellow then magenta (pinkish red) then cyan (blue-green).</p><p>- Toning that appears only on the tops of the lettering and devices and not in the coin&#039;s recesses.</p><p>- Wild &quot;circus&quot; colors -- on 90 percent silver coins, for instance, army green, bright pumpkin orange, and robin-egg blue. </p><p><br /></p><p>From the book &quot;Coin Grading and Counterfeit Detection&quot;</p><p><br /></p><p>- The toning floats on the surface of the coin rather than having depth and being bonded to the metal.</p><p>- The toning occurs over hairlines or other marks.</p><p>- The toning exhibits bright &quot;crayon&quot; colors.</p><p>- The toning has a yellow-brown, smoky appearance, indicating it was caused by cigarette or cigar smoke. </p><p><br /></p><p>Check out this page explaining toned coins:</p><p><a href="http://rg.ancients.info/guide/toning.html" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://rg.ancients.info/guide/toning.html" rel="nofollow">http://rg.ancients.info/guide/toning.html</a>[/QUOTE]</p><p><br /></p>
