it is a Töle Buqa/Talabuga Khan silver dirham, 1.40 gr. , 19 mm.
The tamgha on the reverse is Töle Buqa's.
On the obverse an arab script.
I can recognize the date in the lower line AH: 686 (=1288 AD).
In the middle line the first two characters I guess it means “struck in”.
On the top line it should be the Mint. It has been sold to me as a Qrim (Crimean) mint.
But, based on https://www.numisforums.com/topic/5141-identification-guide-to-islamic-golden-horde-dangs-part-ii-mints/
it looks rather much more like this mint: 
that is the mint of Bulghar followed by something looking like 文 (?)
Is it correct? And what's the meaning of the remaining part of the second line? the Khan name?
thank you for any suggestion you may offer!
