Pocket_Change Valued Member United States 129 Posts	Posted 02/06/2010 09:36 am I recently purchased a '22 Peace dollar for my type set. When I bought it, I noticed it was mottled and just figured it was badly toned. That didn't matter the detail was good and well, I wanted it . When I got it home and out of it's flip. I noticed it wasn't toning, it was something on the surface of the coin. The closest thing I can come to describing it is dried soup. I know at least part of it will come off because I tried with my finger on a small spot and it came up. I tried a soak (about 20 minutes) in hot water but nothing happened. Any ideas on how to get this gunk off? Report this Post to the Staff

It'll jst damage the coin. A little more soaking might also help. It's your coin so the choices are yours. Report this Post to the Staff
Bilbo Pillar of the Community United States 812 Posts	Posted 02/11/2010 3:42 pm If it is organic, acetone should remove it. There are numerous threads on the forum about acetone and its uses. Check them out before you begin. Just make sure you are in a well ventilated area, use a container with a lid (it evaporates very fast) and remember it is quite flammable.

Jaobler Pillar of the Community United States 6383 Posts	Posted 02/11/2010 11:26 pm I wouldn't use an ultrasonic cleaner. The one time I tried that (on a circulated Indian cent) it left the coin with an unnaturally bright color that was worse than the cruddy original. I'd settle for a long soak in hot soapy water or else try the acetone route. Report this Post to the Staff
