Hey folks—new collector here courtesy of an inherited collection. I know enough to know one is NEVER supposed to clean coins, however my great grandfather left me little choice. I’ll explain. He gave my grandmother and grandfather a card for their 25th wedding anniversary in 1953 with 25 Morgan silver dollars. It has one magnetic circular space on the front cover, and inside there are 24 more circular spaces—these, unfortunately required he glue the Morgan’s into place. So, I’ve got 24 Morgan’s with glue on them I’d like to remove. I’ll try to post pics. Any recommendations on how to remove the glue? Goo Gone? Help! TIA!
