<p>[QUOTE=&quot;Insider, post: 7937495, member: 24314&quot;]Our US coins can often be found with a <span style="color: #006600"><b>SOFT</b>, green deposit</span> (usually in a recess of the design) that can be easily removed w/o a trace if caught early enough.&nbsp; Dark dirt deposits occur in the same places but these are rarely soft and using the method I outline below should not be done (you may <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie3" alt=":(" unselectable="on" unselectable="on" /> scratch the coin) as they are removed in another way.&nbsp; </p><p><br /></p><p>ALL treatments such as this should be done under a stereo microscope or magnification that leaves both hands free.&nbsp; We use this method for tiny areas.</p><p><br /></p><p>Take a round toothpick and shave it down to a thin sharp point.&nbsp; Touch the residue to make sure it is soft and not a hard green corrosion spot.&nbsp; If it is soft, gently push the green off using tiny forward motions with very little pressure.&nbsp; </p><p><br /></p><p>Note: While acetone on a Q-tip will also work, the acetone will take the &quot;skin&quot; off the coin and it may on longer look original.&nbsp; &nbsp; </p><p><br /></p><p><br /></p><p>[ATTACH=full]1373316[/ATTACH] </p><p><br /></p><p><br /></p><p><br /></p><p>[ATTACH=full]1373317[/ATTACH][/QUOTE]</p><p><br /></p>
