Unkknown uniface silver coin

[aidab]

Hi,
Once more, I would appreciate any help to identify this old uniface/einseitiger silver coin.
It weights 0,5 gr. and it's diammeter is 15 mm aprox.
I'm not able to distinct if the coin shows a human figure or eagle..or ...

I madea mistake in my description: Weight is 0,4 not 0,5.

Hello,

I think it's an eagle.

Possible:
Brandenburg (Friedrich I. or II:); City Salzwedel, 1415-1470 (?)
