Kushan Kanishka AV Stater (c.AD130-158), a Buddha standing on reverse
The Kushans , a Central Asian people who had settled in Afghanistan during the second sentury BC, extended their empire into India during the late first century AD. By the end of the second century AD their coinage was well established in Northern India and had a considerable influence on local coins.
Normally, the Kushan coins depicted the potrait of the Kushan King on the front, normally as a full-length figure sacrificing at an altar, but on some issues riding on an elephant or seated on a throne. The back always showed a god or goddess. Both sides were inscribed in the Kushan language written in Greek script. Coins were struck in both copper and gold, the first time gold coinage has been issued in India. The copper coins were imitated in many areas, both unofficially as in Orissa and officially by local tribal groups like the Yaudheyas and Kotas in the Punjab.
