Unknown Silver Pfennig -Eagle in shield

[aidab]

Hi,

This silver piece weights around 0.6 gr and it's diammeter is between 14-15 mm. In one side presents an Eagle in a Triangle shield between two towers and in the other shows a human figure (warrior ?) holding two
spears, one in each hand.

I would appreciate any help to identify it.
