Æ Unit - Nahapana

Nahapana ruled the Western Satraps in the late 1st to early 2nd century AD and is among the best-documented rulers of the dynasty through both numismatic and literary sources — the Periplus of the Erythraean Sea names him directly, placing his territory along the northwestern Indian coast and inland trade routes. His reign ended badly: the Satavahana king Gautamiputra Satakarni defeated him and, according to the Nashik cave inscriptions, deliberately restruck enormous quantities of Nahapana's silver coins as a political act of erasure.

Copper units of this type circulated at the local level where silver didn't reach.
