GREAT MONGOLS: Anonymous, AR dirham (3.19g), NM, ND, A-1978K, on the obverse in Persian, be-qovvat-e aferidegar-e 'alam, "by the power of the Creator of the world ", and citing the caliph al Mustansir (AH623-640) on the reverse, lovely VF, ex M.H. Mirza Collection. Struck during the reign of the Great Mongol Ögedei or very shortly afterwards. The presence of the name of the caliph al-Mustansir does not imply that the coin was struck during his lifetime, as many Mongol and later issues often cite a deceased caliph, just as American coins cite a deceased president!

Estimate: USD 110-140
