Hmm, "Groschen" was the colloquial term for a German 10 Pfennig coin. But if you have a coin that actually says "Groschen", it will be from Austria ... As for the value, here in DE you could take the Federal Republic coins to the central bank and get a little less than €1 for them. Unless you have a proof piece or some exceptionally rare year/mintmark combination, they won't be worth much, sorry. Christian
