<p>[QUOTE=&quot;desertgem, post: 718072, member: 15199&quot;]Generally when someone talks about a recolored copper coin, it is assumed they were chemically dipped before someone tried to recolor them. Using any acid type product on the coin will take all patina off of the coin so it has that pinkish tinge of a 2009 cent fresh, really fresh from the mint. Any coin more than a few months old will have a golden tinge to the patina. The acid is used to try and take off any spots or bad toning or corrosion damage.</p><p><br /></p><p>Now obviously, no one would believe a 1909 cent that was pinkish, so they try to recolor these back to the &quot;old time&quot; look, and it can seldom be done quickly ( some say not at all), and the cent comes out orange or weirdly toned. They usually remind me of Halloween Lincoln pumpkins</p><p><br /></p><p>Acetone, xylene, 90% isopropyl alcohol will not change the color of the metal. It may however remove oils, grease, gunk that had covered parts of the coin for a long while and when removed, shows a different color to the metal than before.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
