hello together, I don't know if someone around here has a clue from medieval German coins, but i just try my luck.. This one was found in Baden-Württemberg, should be Silver or Billon and looks like one side minted..but I'm not really shure about that, even if I brought them Pictures in the exact position.. I know, it is a little away from the States..so I think "pigs might fly" for this one. kind regards, Niloc
Not a whole lot there to judge on, but I recommend ALWAYS supplying size and weight data to help identification.
I cant really make it out, but it looks to me like a French coin. Compare http://home.eckerd.edu/~oberhot/fp3bg.jpg which is not the same coin, but displays a similar altar design on the reverse and is a Gros Tournois from Louis XI (1226-70). Hope I'm not sending you on a wild goose chase.
