32 rati - Muhammad Shah

The Jaunpur Sultanate occupied a politically volatile stretch of the mid-fifteenth century, wedged between the Delhi Sultanate and the rising power of the Sharqi dynasty's own ambitions in the eastern Gangetic plain. Muhammad Shah ruled during a period of near-constant military pressure, and the billon coinage of this reign reflects the fiscal strain — the debased silver content of surviving pieces varies noticeably, suggesting irregular bullion supply rather than deliberate policy shifts.

The 32 rati weight standard derives from the traditional Indian ratti seed measure, with 32 ratti approximating the masa unit used across north Indian minting practice of the period.
