Unknown old silver coin - to identify

[aidab]

Hi,
Once more, I would appreciate any help to identify this old silver coin.
It weights 0,8 gr. and it's diammeter is 22-23 mm aprox.
It looks like a sun with 10 rays ? in one side

Hi,

that's a "Dünnpfennig" from Augsburg, Hartwig I. von Lierheim 1167-1184.
Ref.: Steinhilber 46
The reverse usually is not well struck so one could think it's uniface, but it isn't.

Bye,
Peter
