Need help identifying ancient greek coin [решено]

Hello,

Today I received a new antique coin. Here again the problem: I can't identify it, although I know the region (Seleucid Empire). I therefore hope that it is correct. That's why I wanted to ask you for help. I apologise for the reflections, that's one of the best things I can do.

Thanks in advance.

backside rotated by 90 degrees

Weight: Can't say exactly as this is in the pictured case

Diameter: 18mm

I just wanted to bring this post back up through this comment. Just in case someone still manages to identify this coin.
