1 Rupee - Chakradhwaj Singha with lion

Chakradhwaj Singha ruled Assam during one of its most militarily significant periods — his reign saw the decisive Battle of Saraighat in 1671, where the Ahom general Lachit Borphukan repelled a massive Mughal naval assault under Mir Jumla's successor Ram Singh I. Assam was one of the few regional powers to successfully resist Mughal expansion, and its coinage reflects an administrative confidence that most contemporaries under Mughal pressure could not sustain.

Ahom silver rupees of this period followed the Mughal weight standard closely, a pragmatic acknowledgment of regional trade realities rather than submission to Delhi.
