<p>[QUOTE=&quot;BadThad, post: 1355173, member: 17261&quot;]We&#039;ve discussed this before....it&#039;s a mystery with a lot of theories. The best I can come up with is contamined roller press. I think the actual alloy is correct, but impurities are introduced during the planchet manufacture. I suspect just one of the rollers was usually contaminated, but sometimes both.....thus we have one sided and double sided LMC woodies.</p><p><br /></p><p>Doug, did your harshly cleaned LMC retone yet? I think it&#039;s been a year![/QUOTE]</p><p><br /></p>
