I got some of those from different years, I think this is the scarcerst
1/8 Ducat 1688 / 1/8 
Dukat 1688 , Vratislav / Breslau, 0,54 grams of gold, 12 mm Aprox, Au, S. Hammerschmidt, Herinek: 536, Friedberg: 298

Surface of both sides circulated

Bought in Germany to an Ebay collector in 1999

Probably a restrike Official contemporaneous , although it is clearly circulated.

Very hard to make a good picture, is too tiny (12-13 mm) for my camera and not enough resolution.
