<p>[QUOTE=&quot;Boss, post: 612292, member: 15110&quot;]I did both of these on my suggesstions- thumbing- handling the coin, and and dellars. The thumbing put a near permanant set of prints on coin and NCS got most of it off. Dellars caused black carbon spots as the sulfur in it had coagulated into little pockets of concentrated sulfur the size of pin points (I lacked the knowledge that this can happen, but inspected the Dellars after these incidents). This caused two of my keys to break out in black carbon spots- my S VDB and 1914 Lincolns. Got all off the S VDB with Verdigone. On the 1914-cut in half the size of the spots but caused about 5 or so brand new carbon spots. </p><p>&nbsp;</p><p>When you use Verdigone on black spots it diffuses the carbon over the whole coin and causes a greying look- the longer you leave in the worse it gets but the spots go away. I post this to help you learn. Always mix the Dellars with a q-tip or tongue depressor and whip up like whip cream. Dilute with regular 100% white petroleum (Vasoline). Dellars is too strong (10% sulfur) and causes the painted on look. I have found that albums and paper flips tone nicely. Use xylene first to remove oils to cause quicker toning (oils inhibit this). Let us know what you do. Cool coin and it definitely needs some toning.[/QUOTE]</p><p><br /></p>
