A German friend was looking for some coins dated 1979 (his son's Birthyear). I have trays and trays of 1, 2, 5, 10 Pfennig etc with many duplicates, so I told him to look through and take what he wanted. He took 10 coins he liked and then offered me this in return. I couldn't refuse as he insisted. 1990 10DM proof. 400,000 struck in .625 silver. First an image of one of the trays and then the coin.
