<p>[QUOTE=&quot;ksparrow, post: 2253828, member: 7638&quot;]A question for our resident chemists.&nbsp;&nbsp; I remember reading that a number of the Bass collection gold coins had pvc, but I never saw proof that the coins were damaged. Given that coins are made from a gold alloy, could the HCL produced by the PVC plasticizer and humidity actually corrode the surface of them?[/QUOTE]</p><p><br /></p>
