<p>[QUOTE=&quot;fiddlehead, post: 1226587, member: 31286&quot;]So you would agree that the likelihood is that were the &quot;damage&quot; from cleaning then it would have had to have happened before the grime gathered and coin re-toned? And people here say that acetone doesn&#039;t remove metal from the coin - if that&#039;s true it would have to be some other cleaning agent, no?&nbsp; Like which ones?&nbsp; </p><p><br /></p><p>How about other sources of damage besides intentional cleaning, which given the grime and likelihood that it is a circulated coin, would seem possible - or even likely.&nbsp; What about exposure to chemicals of some kind at a worksite? If so, what kind of chemicals could do that light pitting?&nbsp; </p><p><br /></p><p>And if it was poor dipping technique, how could it be much more prominent on one side of the coin than the other?[/QUOTE]</p><p><br /></p>
