I found in an box of stray old coins this silver one: AR 25 mm, 4.01 g After a quick search on AC Search, I think it is a coin of 2 dirhams in the name of Öljaitü (also spelled Uljaitu), a descendent of Genghis Khan, Ilkhanid ruler of Persia AD 1304-1316. ... but I cannot decipher the mint. In case this post is seen by some specialist, thanks a lot in advance !
Arzan al-Rum (Arzarum/ Erzurum) mint, dated Ramadan 704. The mint signature is located between lines of the Kalima in the left image (duriba Arzanalrum): ضرب ارزنالروم The month is located in the right margin of the right image (fi Ramadan): في رمضان The year is in the left margin of the right image (sanat arba' wa seb'mi'at): سنة اربع و سبعماىة Fortunately, number 104 in volume 9 of the Ashmolean Sylloge (SICA-9) is precisely your coin. al-Rum means "[land] of the Romans", which was the Muslim name for Anatolia.
