Hi
It is
Islamic, a coin of the Artukids of Mardin, Nasir al-Din Artuq
Arslan, 597-637 H/ 1201-1239 AD.
There are two varieties of this, with four or five lines of
inscription on the
reverse, and yours is the four line one,
Spengler & Sayles 37.1, struck in 598 H/ 1202 AD. The
reverse is upside down in your photograph.
The six pointed
star is a Muslim symbol as well, known as the 'Seal of Solomon'.
Best wishes
Alan
