<p>[QUOTE="jaceravone, post: 1812744, member: 9474"]Here is my situation. First let me say that I am not a copper collector. Personally, I hate all copper coins. Its not that I don't appreciate them, because I do when I see a nice one, but they are so reactive and they require a lot of care that I don't like to even touch them.</p><p><br /></p><p>I acquired a really nice 1 oz copper medal a while back from the Mulligan mint. Since I obtained that item, they started to produce these copper rounds for bulk sale, whereas the original copper round that I got was a promotional item. When I received the promotional copper round it had a bunch of finger prints on it. So yesterday after doing many searches on the internet for ideas on how to remove the fingerprints, I decided to try a few of them out. After using things like MS70, Ketchup, lemon juice, I noticed the copper round becoming more and more reactive. After several hours, the copper round started tarnishing/toning a dark brown color. In total desperation, I dipped the round in silver dip which restored it to its natural color, but only to turn even worse after a few hours of sitting. When I woke this morning, it was horrendous looking. So in complete distraught, I dipped it in silver dip and put it in a bowl of acetone to stabilize it. So far so good, but I am afraid to see what happens when I take it out. </p><p><br /></p><p>So does anybody have any suggestions or recommendations? Is it too late and have I destroyed this copper round. </p><p><br /></p><p>So you may ask the question....whats the big deal about this copper round....well....its a mule. They used their silver round die to make the promotional ones, then made new dies with a small tweak on the new ones. If you would like to see the rounds, go to my website listed below and click the exonumia tab. Scroll down to the copper Sentinel round. They are not marked, but hopefully you will catch it. The silver one is in the next row beneath the copper ones. </p><p><br /></p><p>Thanks for any help.[/QUOTE]</p><p><br /></p>
