1 Rupee - Siva Singha and Pramateswari Devi

Siva Singha ruled Assam as the last great Ahom king with genuine political authority, and the co-inscription of his queen Pramateswari Devi on coinage was a deliberate assertion of her status as co-regent — a practice with almost no parallel in contemporaneous Indian numismatics. The Ahom kingdom had minted silver rupees in its own script and language for generations, a conscious rejection of Mughal monetary conventions at a time when nearly every other regional power had adopted them.

KM#74 is among the more frequently encountered Ahom types, but genuine examples still require careful authentication — the series has been extensively reproduced.
