The coin had considerably more gunk when I bought it from the LCS but most of it is gone with a half-day soak in acetone. Should I try soaking it longer? Report this Post to the Staff

If it was mine, I wouldn't bother. Some ancient coins require this kind of treatment after initial cleaning, after recovery from ground burial. What remains (the black stuff), is most probably a silver sulfide / oxide combination. Acetone or any other organic solvent has zero effect on the inorganic oxides or sulfides of silver. Mechanical removal may help, but if you are ham fisted in your attempt to remove any of the black stuff, there is always some risk involved.
