samx3 Posted November 5, 2012 Report Share Posted November 5, 2012 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? Quote Link to comment Share on other sites More sharing options...
jlueke Posted November 6, 2012 Report Share Posted November 6, 2012 How are they ruined, are they corroded? Quote Link to comment Share on other sites More sharing options...
