Debased Dinar - Balabhata Khadga dynasty

The Khadga dynasty ruled Samatata — the deltaic region of Bengal, roughly modern southeastern Bangladesh — from roughly the mid-seventh century, and their gold output reflects the broader monetary degradation visible across post-Gupta Bengal. By the late seventh century, access to pure gold had become severely constrained for regional powers lacking the trade revenues of their imperial predecessors. Balabhata, likely the third ruler of the line, issued dinars that imitate the Gupta weight standard in name only — the actual fineness drops markedly, alloyed with silver and copper to extend the supply.

Khadga coinage is extraordinarily rare in any form. Most surviving examples come from hoards recovered in Comilla district.
