The thing that can also change the value is the letter that is on it. A, B, D, E, F, G, and J are all letters that are on German coins. This one looks like a D, and its value is around $.20.
The letters represent the mint mark.
The "D" mintmark represents Munich.
The "J" mintmark in the coin I referenced is from Hamburg, the home port of the mighty ship 'Bismark' that sunk the 'Hood' in WW II--but I digress.
Don.
You are right Don, my bad! I was seeing the hole in the "1" due to corrosion eaten into it and thought that is was a 5 Pfennig piece. I should have looked closer!
