Welcome to Numista!

I can offer a couple of pointers to hopefully get in the right direction. To my knowledge there are only two places in India that produced this shape of coin. One is the princely state of Hyderabad and the other is the Elichpur mint. Maybe another member will be able to make a more complete attribution. 

Quite a few  lndian states produced this shape, Awadh, Jhalawar, Kotah, Bundi, some of the Sultanates etc
