⅔ Falus - Ahmadnagar Sultan

The Ahmadnagar Sultanate, founded by Malik Ahmad in 1490 after breaking from the Bahmani Sultanate, maintained a fractional copper coinage that served local market transactions the silver-dominated treasury issues could not practically reach. The ⅔ falus denomination is an unusual fraction — most Islamic copper series in the Deccan worked in halves or thirds independently, not combined — suggesting a pragmatic monetary adjustment to local purchasing conventions rather than any centralized imperial directive.

Ahmadnagar was the last of the five Deccan Sultanates to fall to the Mughals, holding out until 1636 largely through the efforts of the regent Chand Bibi and later Malik Ambar.
