If I were to make a dumb guess --not entirely out of character (snort)-- this might be Ayyubid (the dynasty founded by Saladin; ruling in Egypt, Syria and elsewhere into the mid-13th c. CE). That's solely on the basis of the central squares, a common motif in Ayyubid AR dirhams. ...Likely denomination along the lines of a fals (the Arabic derivative of the follis). But somebody who can actually read Arabic will need to weigh in.
It's from the Seljuks of Rum. On the left side the name of caliph al-Musta'sim. On the right the name of ruler Izz al-Din Kayka'us (II), 1245-49AD.
Al Musta'sim was the last Abbassid Caliph. He was overthrown and murdered by Hulegu who devastated Baghdad in 1258 AD. The latter was the grandson of Genghis Khan, founder of the Monghol Dynasty. Hope that would help a little.
Just for fun and for those learning to read Arabic coins, the legends are: الامام المستعصم بلله امير المومنين السلطان الا عظم عزا لدنيا و الديب al-imam al-Musta'sim billah amir al-mu'minin // al-sultan al-a'zam 'Izz al-Dunya wa al-Din. The caliph's laqab al-Musta'sim billah means "[He] who holds fast to God". amir al-mu'mimin is "commander of the faithful". al-a'zam means "very great". The sultan's laqab 'Izz al-Dunya wa al-Din translates as "Glory of the World and of the Faith". The laqab is an honorific title and a standard part of Arabic names. al-sultan and al-imam have the same meaning in English as in Arabic.
@dltsrq, that was Hardly "just for fun." This is the heart and soul of what ancient and medieval coins Should be about: miniature historical documents. You just Nailed it. Thank you.
@+VGO.DVCKS Well, it started out as fun with the Arabic keyboard on my phone. Then the coffee kicked in.
