<p>[QUOTE=&quot;desertgem, post: 772676, member: 15199&quot;]It really depends on the type of coating material available when it was done. If it was done in the 30s-40s, then it was probably natural shellac material from certain insects or plants. Then came synthetics which were harder to remove, and then acrylics which are almost impossible to remove. Since it is a key coin, I would either leave it alone or use NCS to investigate it if you do not know exactly what type of coating it happens to be. If it is acrylic based, it can look bad, no matter who does it.</p><p><br /></p><p>Jim[/QUOTE]</p><p><br /></p>
