<p>[QUOTE=&quot;gc1111, post: 177883, member: 4142&quot;]I had some coins I tossed in a baggie on my boat during a Caribbean trip. When I came across them years later they had developed something that sounds like your problem. One was a silver coin with&nbsp; what looked like a layer of thick iron rust. This was a common date Washington quarter so I decided to clean it. After starting mildly, I ended up with some pretty strong cleaning. And the coin underneath was seriously eroded. I came to the conclusion (just a best guess) that it was electrolytic corrosion caused by a couple of pure nickel Canadian quarters in the bag. However there was also a variety of Bahamian coins, some copper, in the mix.[/QUOTE]</p><p><br /></p>
