Islamic but fom ?

[aidab]

Hi,

This one weights 3 gr. and it's diammeter is 26 mm
Obviusly by it's characters this coin seems to be islamic but I have no idea of which area and what era/ruler belongs ... may be someone can help me.

Looks like an Abbasid coin from that territory which is now Iraq. An exact determination will take some time; perhaps sime days later.
Regards, Afrasi
