<p>[QUOTE=&quot;Conder101, post: 4573182, member: 66&quot;]The coin he is talking about supposedly has very recent fingerprints.&nbsp; Acetone may or may not remove them completely (frankly I would use two baths, one of acetone to remove organics, and one of distilled water to remove salts.&nbsp; Then a finial acetone rinse to dry the coin.)&nbsp; One word of warning, copper often takes on a slight film of oil and the acetone will remove that.&nbsp; It could leave the coin &quot;dry&quot; looking.[/QUOTE]</p><p><br /></p>
