<p>[QUOTE=&quot;GDJMSP, post: 94166, member: 112&quot;]There is still green stuff on the coin. It is either PVC residue or verdigris. Acetone will dissolve the PVC - it will not remove verdigris. It may well loosen the verdigris so that you could pick off the top layers of the corrosion, but it won&#039;t completely remove it or stop it from continuing to corrode the coin.</p><p><br /></p><p>I have posted several times about a commercial product that will remove verdigris - you can buy it here <a href="http://dirtyoldcoins.com/store/product.php?productid=12&amp;cat=2&amp;bestseller" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://dirtyoldcoins.com/store/product.php?productid=12&amp;cat=2&amp;bestseller" rel="nofollow">BIOX</a>[/QUOTE]</p><p><br /></p>
