<p>[QUOTE=&quot;SuperDave, post: 2634398, member: 1892&quot;]The point to acetone and copper is more nuanced than &quot;four legs good, two legs bad.&quot; [USER=27832]@-jeffB[/USER] has it correct from a chemistry standpoint, aside the fact that in addition to the strong light, water or heavy vapor also need to be present. Copper gets the same soak in acetone for me as does <b>every</b> raw coin I purchase.</p><p><br /></p><p>Here&#039;s how I have them:</p><p><br /></p><p>1863: AU53. Strong strike, pretty much everything I see is wear.</p><p><br /></p><p>1884: EF40, weakest strike of the three.</p><p><br /></p><p>1883: EF45. I don&#039;t think either of the last two will straight grade, which doesn&#039;t mean I don&#039;t like them. <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p><br /></p><p>Edit to ad: I see nothing on the bottom two which makes me think intervention with either acetone or Verdicare is warranted. The top one needs to see some Verdicare, though.[/QUOTE]</p><p><br /></p>
