1/2 Rupee - Pramatta Singha

Pramatta Singha ruled Assam during a period of relative Mughal disengagement from the northeast, allowing the Ahom kingdom to maintain its own coinage tradition well into the eighteenth century — one of the last Hindu kingdoms in the subcontinent to do so independently. His reign ended in 1751, and the silver coinage struck under him reflects the Ahom practice of dating by regnal year rather than a fixed era, which makes precise attribution within the issue window dependent on die analysis rather than inscription alone.
