The reverse is the mint and date written out in words. This type was struck for decades with all coins bearing the frozen date 874, the primary difference between issues being the names of the several successive sultans in the lower half of the obverse below the knot. The sultan's name isn't plain here but if I had to guess I'd say Hasan Shah, 1472-1484, G/G K32. The apparent difference on the reverse is likely a matter of the arrangement of the legend and the strike.
