After the death of Abu Saeed (716-736 AH. / 1316-1336 AD.), the last ruler of great Mongol Ilkhanid, Sarbadars (737-783 A.H/ 1337-1381 A.D) who were amongst the effective uprising local groups had succeeded in forming a government and due to some circumstances they had to adopt various religious policies. The aim of this research is to answer this question in a semiotic approach that how was the process of Sarbadars’ religious policy? The findings of this research shows that at the beginning years the coins of Khurasan Mongol kings were circulated as the sign for acceptation of Ilkhanid’ ascendency and in the second period Sarbadars had minted coins with no name similar to the style of Sunnies which spoke of their tolerance and counsel. Coins of the third period had signs of a theocratic fundamentalism system and sometimes there were exaggerations that the name of Imam Mahdi (A.J) is depicted as Sultan al-Muhammad Mahdi. This is a term which had not been and is accepted amongst the Twelver (Ethna Ashari).
