Cleaning Coins, Properly

Have you tried to lick the sticky stuff off? Just pop it in your mouth and imagine that it is a life savor. Just kidding.

I have used a small amount of Googone on a few coins. It easily removed the gunk from the coin with no adverse effects. Just be sure to clean it after with some distilled water and a mild soap. Googone is mild and non corrosive. Should do the trick for you.

You can use a rose thorn or softened toothpick to work around......having a brain fart and lost the word I'm looking for. To work around the letters/date or whatever other nooks and crannies you need to get at.

I reformulated the original Coin Care product for safe copper cleaning.

For what you described on the coin, acetone should do the trick..... And is 100% harmless to the coin... That would be my absolute first try then move up to other things if need be, but definitely not vinegar nor scratching it. Me personally.... I'd try acetone and if not I'd send it in as is and pay for them to do a conservation.
