Journal Article 2024 04 18 Because coins are available to everyone to use in trade, their analysis and comparison can help us better understand some historical ambiguities during the reign of Shah Ismail and the role of Great Khorasan as one of the important states with a high distribution of mints. Mints which represented the economic power of the government, were established in cities by economic, political, military and communication importance. Political changes had a direct effect on determining the weight of coins in a mint. This research aimed to study the weight and diameter of coins and investigate the economic situation in Greater Khorasan. Because the weight of coins is valuable in socio-economic discussions. Therefore, this descriptive-analytical article using the historical method and study of numismatics and Khorasan mints, tries to answer this question: what are the effective factors in the extreme changes in the weight of coins in the period of 916-928 A.H. (1510-1522 A.D.) The results show that political and economic events affected the minting of coins, and the government prevented inflation and established economic balance in trade affairs by decreasing and increasing the weight of coins.<br /> <br />.
