Based on the weight and general appearance my guess would be a half falus (on the 96 rati standard) of the Sultans of Gujarat. It looks like there's a date of AH 966 (at 3 o'clock on the first photo). However, a quick look through GG and Zeno didn't reveal a match to my eyes.
Thanks Seekers.
I went over all the Gujarat coins on Numista and could not find an exact likeliness but at least I have 6 data points:
Gujarat, Copper, 5.6 gr, 13 mm = 1/2 Falus and 966 or 1558.
Now at least I can put it in the right place.
Thanks,
Ben
