I ordered some quills and they should arrive soon. I will get some acetone. How long would you soak the coin or coin in acetone before taking them out.

Also, would you rinse then with sterile water or deionized water?


Thanks

The quill or plastic idea is a good one, but keep in mind that the "gunk" might be abrasive and the quill might rub some on the coin.

No rinse in water is required, if you soak in acetone it's best to let the acetone air dry from the coin.

As for soaking time, it depends on how thick/greasy the stuff is. Generally an hour would be more than sufficient

Leave your coin in the Acetone for approximately 10 years. Then rinse with Sulfuric Acid but be careful with that. A wire wheel on a bench grinder would help also.
All just kidding. If you don't have to, don't clean coins. Yours is mostly just what may be Machine Doubling which is not the same as a double die coin. If you really want to clean it, just a few minutes in Acetone is about all you need.
