1 Rupee - Sher Shah Suri Jahanpana Type

Sher Shah Suri's rupee was not simply a coin — it was the architectural decision of a monetary system. Introduced after his defeat of Humayun in 1540, the standardized silver rupee of 178 grains became the template that the Mughal emperors would later inherit wholesale, and that the British East India Company would still be referencing three centuries later. The Jahanpana type specifically dates to the middle years of his reign, when his administration was consolidating revenue collection across a newly unified north India.

Sher Shah ruled for only five years before dying in a gunpowder explosion at the siege of Kalinjar in 1545.
