I was looking at some of my late grandmothers early penny (Indians and wheats) and silver coins that were stored in these brown 3 ring binder books that had PVC pages with the year and mint marks marked accordingly for each coin - anyway, I took one out and noticed there's a slimy residue on all of the coins - any "safe" way of removing this residue? Safe meaning if it was to be graded it would not be graded as "cleaned" - Thanks.
