Indo-Sasanian coinage was major type of coinage of the post-Gupta Empire period, in the areas of Gujarat and Rajasthan in western India and in the Gangetic region, from the 6th century to the 12th century CE.
[1][2] These coins were derived from the Sasanian coinage design, probably transmitted to the subcontinent by the Alchon Huns as they invaded northern India circa 500 CE.
Indo-Sasanian coins derive from three Sasanian prototypes, which were introduced in western India by the Alchon Huns, also called Hunas by the Indians.
[1] Indo-Sasanian coinage covers a period of several centuries, during which it is possible to see a progressive degradation and stylisation of the original Sasanian design, in ways which vary according to the region where they were current.
[1] Around the beginning of the 9th century, coin designs derived from the Sasanians were adopted in the Gangetic region: the Vigrahapala drammas of a certain ruler named Vigrahapala , and later the Adivaraha drammas of the Gurjara-Pratihara ruler Bhoja I (c. 836-886 CE).
