<p>[QUOTE=&quot;Beefer518, post: 2830150, member: 87737&quot;]The bold section is sort of why I asked this. I was reading another thread (here or somewhere else), and it seems a LWC developed an ugly carbon spot right on Lincoln&#039;s cheek, after it was slabbed. One hypothesis was that a grader sneezed or something, and some organic matter (eww) got on the coin during the grading process. At which point it was suggested that the TPG&#039;s could offer an acetone dip just before slabbing. </p><p><br /></p><p>I like the idea of giving every raw coin an acetone bath, and I think I&#039;ll start doing it.[/QUOTE]</p><p><br /></p>
