<p>[QUOTE=&quot;BadThad, post: 523163, member: 17261&quot;]I don&#039;t understand why you&#039;d use VERDI-GONE™ on this coin, I don&#039;t recommend that at all, I see no verdigris. The only thing VERDI-GONE™ should be used for is removal of verdigris, it&#039;s not designed for anything beyond that.</p><p>&nbsp;</p><p>I agree with desertgem, soak it in olive oil for a few weeks, clean that off with xylene, then put it in a window sill for months to retone. Periodically rub the coin between your fingers and flip during the retoning process. This coin will probably need over a year to oxidize.</p><p>&nbsp;</p><p>Sorry Harryj, I disagree, DO NOT BAKE THE COIN, whatever you do IMO. Heating Lincolns is a very bad idea, I&#039;ve experimented with it and the results are not good. Try it for yourself and see. The zinc/tin tend to come to the surface because they have MUCH lower melting points than copper. Here&#039;s the difference:</p><p>&nbsp;</p><p>Tin 232°C</p><p>Zinc 420°C</p><p>Copper 1085°C</p><p>&nbsp;</p><p>Once the appearence changes to the &quot;silvery&quot; color, the coin is completely ruined. The alloy mix will never be the same.[/QUOTE]</p><p><br /></p>
