<p>[QUOTE=&quot;medoraman, post: 1232761, member: 26302&quot;]Just asking a question so please do not throw internet rocks. Is it really toning if it is on a non-reactive metal? What I am saying it, if these chemicals were in the leather, did those chemicals actually tone, (tarnish), the coin or are they simply laying on the surface of the coin? I understand there is some silver and copper in US gold coinage, are we saying that part toned from the chemical exposure?</p><p><br /></p><p>A follow up question would be if this coin was .999 gold, and same thing. Would that be toning or surface contamination? I thought toning had to be metal activity.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
