<p>[QUOTE=&quot;BadThad, post: 997257, member: 17261&quot;]Obviously, something is causing it over and over. Mostly on one side, less often on both sides. Right now I can&#039;t say if it&#039;s a mint process or post-mint. I can tell you this, Doug is wrong about being able to &quot;see&quot; the woodgraining on a fresh coin. Unless he has a EDXRF built-in to his eyes, there&#039;s no way in hell somebody could see this until toning begins. It&#039;s the difference between the poorly mixed copper and well mixed copper that creates the graining effect. The difference is so small that you won&#039;t be able to tell until the coin tones. At that point, the metals react differently to the gases the coin is exposed to.</p><p>&nbsp;</p><p>Right now my best, educated guess is that something was getting to the surface when the planchets were prepared. It could be that either the top or bottom roller was contaminated and &quot;pressed&quot; the contaminant into the planchet. These modern woodies just don&#039;t look anything like the improperly mixed allow woodies from the 20&#039;s-30&#039;s. I don&#039;t think they are caused by poor alloy mix.[/QUOTE]</p><p><br /></p>
