No information when I bought it. From the size and shape my assumption is Indian Princely States. Composition is copper. Weight is around 10grms give or take guessing without a scale. 16mm wide. 4.5mm thick. One side is very worn but the characters almost resemble a flower pattern. The opposite has visible lines across that have a trident shape.
If you're lucky maybe one of our members very experienced with Indian coins may recognize it. Personally I would not attempt an ID without better photos and a weight to the nearest tenth of a gram.
Edit added later: I was typing this while Geison was adding his comment, so I had not seen it. He may well be on the right track.
