<p>[QUOTE=&quot;jcuve, post: 699394, member: 13945&quot;]I mean no disrespect when I ask this, but where can I read about this phenomena discussed &quot;Plating shift doubling?&quot; Mike Diamond claimed in another thread there was no such animal. I haven&#039;t heard of it and when I googled the term all the links pointed to <i>CoinTalk</i> threads. I am willing to entertain it, but would like a link or a book that details the hypothesis/theory with some evidence (if possible) so I can understand it better.</p><p><br /></p><p>Looking at the auction earlier I was on the fence as to whether it was machine doubling or die deterioration doubling as the lighting was catching so strongly on the doubled area in the seller&#039;s blurry photograph. I could be wrong and it could be this &quot;Plating shift doubling,&quot; can someone elaborate?[/QUOTE]</p><p><br /></p>
