However, quite a few of them got a sticky substance like tree sap from pine trees, which would make somewhat sense, considering my late grandfather lived in a forested area with Pines. my question is, would it be saving off to soak them in hot water with a bit of Dawn Dish soap? I know it doesn't have any harsh additives as I have read the contents and it's widely known that it is used on wildlife and other animals. Even though, I have just always heard never never never clean a coin so if I could get some input on this matter, I would greatly appreciate it! By the way, the community has been excellent so far Report this Post to the Staff

It's a trial and error method but it may help. Good luck! Report this Post to the Staff

Zurie Pillar of the Community United States 5689 Posts	Posted 01/21/2025 3:39 pm I would start with a long soak in distilled water, but without any added soap. That will likely dissolve a lot of sticky materials. If that doesn't work, an acetone soak would be reasonable. Report this Post to the Staff
