If those coins are not valuable, you may just try items around the house such as Lemon Juice, Orange Juice, dish soap and almost anything that dissolves oils. Then rinse with distilled water but again, if not valuable, just rinse with tap water and dry.

Yes, some are worth something--and I want to remove the (inert) mineral oil because I'm going use Verdi-Gone on a few. Thanks everyone for your help and ideas.
