Sounds like you removed soot from it (not patina) and were lucky. Never rub a coin with anything - period. In this case it appears you have a cleaned coin that somebody "burned" to cover the surface problems. What's left looks like XF Details - Harshly Cleaned. Anyways, acetone can't hurt at this point. Not trying to rain on your delight, just being honest that this piece isn't worth much as the numismatic value is all but gone.
P.S. Believe me, I've had similar experiences in the past.
