1 Tanka - Nasir Al Din Mahmud Shah

Nasir al-Din Mahmud Shah III ruled Bengal for over two decades, a reign marked by relative internal stability that allowed the sultanate's mint infrastructure to function consistently — which is precisely why his tankas appear with some regularity in the numismatic record. Bengal's silver coinage of this period drew on supplies routed through trade networks connecting the delta region to mines further north and west, and the tanka weight standard had by this point been well-established through successive sultanate administrations.
