I have tried to find similar coin from Numista and 1 Rupee - princely state of Awadh KM103 is about similar, but has a bit different reverse marks. Especially my coin has a "flower" on the right side of year 26. On obverse my coin has a year 1229.

Weight 11.1 g, diameter 23.2 mm, thickness 3.1 mm. Most probably silver coin.
Any help would be nice.
