Brandmeister Pillar of the Community United States 6520 Posts	Posted 05/24/2023 7:58 pm After 27 hours in the acetone, this is the result. Aside from some faint cleanup of the nickel, there was really no change in the coins. So I broke out my Toothbrush of Value Destruction +2 and scrubbed away. DO NOT DO THIS TO YOUR COINS. That cleaned the red ink right off the quarter. It didn't help the nickel, so I scrubbed it hard against a dry Scotch Brite scouring pad. As before: DO NOT DO THIS TO YOUR COINS. I am rather puzzled by the copper surface of the nickel. Did some kind of severe environmental damage preferentially strip the nickel and leave copper behind? I almost wonder if someone burned it in a fire, or dug it up at the beach where it was attacked by salt water. Before anyone says it: I know, I know, you want to know the mass. I don't have a gram scale handy. I will find one soon and post the results. Report this Post to the Staff
Dearborn Moderator United States 96386 Posts	Posted 05/24/2023 9:24 pm Well the nickel is actually 75% copper and 25% nickel and in some conditions the copper can 'migrate' to the surface of the coin and giving it this coppery appearance.
