<p>[QUOTE=&quot;SuperDave, post: 2301137, member: 1892&quot;]Here&#039;s the thing: When a coin tones &quot;naturally,&quot; it tends to tone somewhat evenly in a geographical sense. It&#039;ll avoid devices in many cases, but proceed equally over the surface where it propagates, not caring about device intersections. Like album toning proceeding evenly from the perimeter inward.</p><p><br /></p><p>I&#039;ve noted dipped coins (which we know to be prone to quick toning if you&#039;re not careful for the first few weeks of storage) can sometimes form toning first around device edges and proceed outward from there. That&#039;s why it&#039;s a red flag for potential dipping to me. Exceptions, of course, exist.</p><p><br /></p><p>But the coin starts toning near devices, and gets thicker/darker in those areas first as well. When you then re-dip the coin, those areas closest to the devices will be the last to lose their toning, requiring more time than peripheral areas, and that&#039;s what I think I see here.[/QUOTE]</p><p><br /></p>
