Unknow islamic coin [opgelost]

Hi all,

another one, which I am not able to identify (or to recognize the right orientation :-( )

Does anyone know more about this coin (age, origin, orientation, etc) - Thanks a lot for your help on that!

Diameter: 16.2 - 17.2 mm
Weight: 2.8 g

Looks like Ottoman Mangir minted in Constantinople
