<p>[QUOTE=&quot;desertgem, post: 5132177, member: 15199&quot;]Seeing several line marks and also several spots of it on the lower parts, I would suspect copper sulfide formation if none of the above trials didn&#039;t work on it. Copper&nbsp; Cents were extremely susceptible to acids being used to &#039;lighten it&quot;. The ugly bright yellow color if the person was not very careful would also be unacceptable , so they would use Dellner&#039;s darkener to darken it a tiny bit to try to make it look like a Red or Red brown cent. Dellners uses sulfur to change it. Today it seems to be gone and a similar composition is&nbsp; called &quot;Brimstone Darkener&quot;,&nbsp; for use on copper to age it for antique appearance. I would save it like it is,<img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie3" alt=":(" unselectable="on" unselectable="on" />&nbsp; Jim[/QUOTE]</p><p><br /></p>
