Hi friends,
I found this request of help today and I'll try to reply soon.
Sorry, but I don't speak German so I can only reply in English.
In my opinion the coin shown is a nice piece of Hafner H50a set but you should check the lenght of the word "IUSTITIA" on the edge. It should be around 14 mm.
The other typical features of this piece is the Longer Central Feather in the Left Wing of the Eagle, the particular form of the Cross after the date and two little Feathers under the Tail.
I could classify it as a H50a in my collection but your coin as a different position and number of Dots into the two Circle-Head of the Eagle.
Try to take a look to the following link:

The coin could be struck in the 1890-1900.
Please, let me know the lenght of IUSTITIA when you can!
Thanks again for your interest in my opinion.
Juan
