Potin Unit - Nahapana

Nahapana was among the most powerful of the Western Satrap rulers, controlling large territories across Saurashtra and Malwa in the first century CE — until his decisive defeat by the Sātavāhana emperor Gautamiputra Satakarni, who subsequently restruck thousands of Nahapana's silver coins with his own types. That systematic demonetization makes surviving Nahapana issues in any metal historically charged objects. The potin unit occupied the low end of the denomination hierarchy and would have seen hard daily use in local markets, which is precisely why examples in decent condition are scarcer than the silver coinage.
