<p>[QUOTE=&quot;GDJMSP, post: 1390511, member: 112&quot;]Back around 2000, 2001, it was pretty common to find many others on the NGC and PCGS forums giving the same warning about acetone and copper that I give. It was common on other forums as well. The people giving the warnings were experienced collectors basing their warnings on their own personal experiences. </p><p><br /></p><p>But people were always disputing it, discounting the warnings as being baseless. They would cite this or they would cite that saying that chemically acetone would have no effect on copper. Or they would simply say that they had never had any of their coins turn colors. Eventually people just tired of it and would no longer make such comments or give such warnings about acetone and copper. Most will only try and tell people for so long before they give up trying.[/QUOTE]</p><p><br /></p>
