<p>[QUOTE=&quot;Collector1966, post: 1224778, member: 17919&quot;]It might have something to do with residue from the plastic getting on the coins. When I was buying &#039;60s proof sets back in the &#039;80s, I was told that it was better to take them out of the government plastic and put them in inert holders because the government plastic could end up contaminating the coins. I don&#039;t know how true that is, but I do know that just about every cent that I had in those proof sets developed at least one ugly black spot.[/QUOTE]</p><p><br /></p>
