1 Tanka - Nasir al-din Mahmud Shah I

Nasir al-din Mahmud Shah I ruled Gujarat through a period of remarkable commercial expansion, when Gujarati merchants dominated Indian Ocean trade routes from the Swahili Coast to the South China Sea. The sultanate's copper coinage of this period was produced in large volume to service a monetized local economy — quite distinct from the prestige silver issues that circulated in long-distance trade. The Cambay mint was the principal facility, though attribution of specific dies to specific mints remains contested in the literature.

KM# 65.1 distinguishes this variety within a series that saw multiple die configurations across Mahmud Shah's two-decade reign.
