Explanation:

The first coins to bear the names and images of rulers were issued by the Indo-Greeks,  who established control over the north western part of the subcontinent c. second century BCE.  The first gold coins were issued c. first century CE by the Kushanas. These were virtually  identical in weight with those issued by contemporary Roman emperors and the Parthian rulers  of Iran, and have been found from several sites in north India and Central Asia.
