Qarakhanid fals with lush calligraphy

[Pellinore]

A Qarakhanid fals with 'Ibrahim' on the obverse and 'Nasr' on the reverse, both in an circle consisting of ample bulges. I can't read much of the circular legends, but I know what it is: a Bukhara coin issued by khaqan Ibrahim b. Nasr in 433 AH. Kochnev #873, Album 3327.
27.5 mm, 2.13 gr.

You posted a lot lately ! Missed this one.
The  reverse definitely does not read Nasr, but "khaqan" خاقان.
The obverse has "Nasr" or "bin Nasr" directly following after "Ibrahim" in the center.
