a few years ago I purchased a ben franklin medal at an online coin auction from what I have learned of its provenance it was manufactured in the 1930s at the Ben Franklin institute on a steam operated coin press from the 1830s Philadelphia mint the press was converted to electricity I know it says souvenir of Ben Franklin memorial sorry I don't have pictures but the medal is copper and about size of current 1 cent coin I was wondering if it has any value it is in au condition as I recall I spent $3 on the purchase
