Real or fake Ancient Silver Stater of Thebes Beotia

Hi,

I need opinions about the authenticity of this coin, it has 12,13 g and 20,5 mm

 

Thanks.

I suspect it's genuine. Counterfeits don't usually reproduce the shadow effect (as I call it; probably has a more technical term) that you see at the edges of the reverse legend. Essentially they are exaggerated flow line-like lines hiding just edgeward of near-edge devices.

I have not looked up the proper weight in Sear, though. That should be done very early on.
