I asked to know if this coin is a Halfpfennig, but the answer was that probably this coin was carved in Hungary for use in the monetary system of Hungary, probably as a denar.
I want to swap only against medieval hungarian coins that I don't have, on a value of 40 euros. In case of sale, I offer the shipping costs in international letter wih tracking number
Best regards,
Adrien
