<p>[QUOTE=&quot;iPen, post: 2694052, member: 69760&quot;]I kinda like how it looks - I don&#039;t mind tarnish at all, though there&#039;s probably some more things going on that that. I&#039;d still definitely put it in acetone. </p><p><br /></p><p>In fact, one of my 19th century half dollars has some very heavy, dark toning that is still in an acetone bath right now even after <i>several</i> days later, and the acetone is visibly affecting and working on it. Little by little, the dark matter is &quot;flaking&quot; off. I&#039;ve also randomly and carefully swished the acetone around in the bath without moving the coin inside the glass jar, which may help to apply force on the coin.</p><p><br /></p><p>And, it may have had some help with using acetone then Xylene, <i>then</i> back to acetone. Maybe the transitions do something more than simply putting them in one or the other (?). I don&#039;t know. Though, I think mine was more or less a stain, so your situation may be different.[/QUOTE]</p><p><br /></p>
