Dear Amit,
The attribution is correct. Khujista Bunyad (Aurangabad). The 1/32 pieces of this mint are for one reason or the other not that rare. They are offered from time to time, but this specimen is better than most others as it may be dated AH1157/Ry.27.
The regnal year can be observed on the left image and the hijri date on the right image.
