Hello,
My name is Paul from Belgium. Can you help me to identify this old coin? It may be a coin from the German or Austrian states... but I'm not sure…
The first face shows something like a shield :

The design on the second face is very used. We can imagine a bishop (or knight) on the right holding a crozier (or sceptre) in the centre. On the left a rose...

Weight: 0,4 grammes
side of the square : 13,5 mm
metal: silver
Thank you very much for your help.
Sincerely,
Paul
