Yes! You're right, it's Hyderabad. How strange that they're using the exact same toughra as Turkey.
The coin is 31.3mm in diameter, so I've narrowed it down to KM#36 1/2 Anna (1324-1329AH) or KM#47 1/2 Anna (1332-1348AH). The first one is copper, the second one bronze, and unfortunately I can't tell the difference between copper and bronze.
Does anyone know what the date is?
