4 Gani - Ghiyath al-din Tughluq

Ghiyath al-Din Tughluq founded the Tughluq dynasty after overthrowing the last Khilji sultan in 1320, but billon coinage of this type was already circulating before he seized power — the denomination predates his reign and continued largely unchanged through the transition. The Tughluq administration inherited and maintained the fractional billon structure of the Delhi monetary system rather than immediately imposing a new coinage identity, which makes precise attribution to specific regnal years within this window genuinely difficult.
