My father-in-law (deceased in the mid-60's) had a small collection of old 1960's era Canadian pennies that we just came across. He kept them in a glass jar filled with a clear oil (vegitable, olive, etc, don't really know). Presumably he thought this would preserve them. Unfortunately they seem to be ruined. We haven't tried to clean them in any way yet. Any suggestions?
