I have one of those square Bahawalpur coins also, supposed to be a 1923, and yours is in much better condition. So I notice a straight line across the waves from Pakistan to...Tanzania.
Rhodesia And Nyasaland. Hate that haze on this coin. Apparently I made some mistakes with PVC storage over the years? See it only on bronze coins. They were all removed from the holders I used for years, but the damage is done.
