<p>[QUOTE=&quot;desertgem, post: 577229, member: 15199&quot;]If the coin was taken from the original holder and put into the flip and sent to the service, I am at a loss for an answer. Toning is a chemical reaction and such color change can occur in just minutes if the solution is a strong sulfide solution. But I see no way such solution would be used in any normal context, especially since the resulting reaction is very unpredictable. </p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
