I bought this coin a few weeks ago for about $4, labeled as "Khanate of Khoqand".
I proceeded to check all the Khoqand listings on Numista and Zeno, and could not find a match - but maybe I just wasn't looking well enough, and/or in the right places.
(It doesn't help that I can't read Arabic at all, so I just compared the shapes of the squiggles.)
Ultimately, I decided to leave this for other CCF members to identify - surely there should be enough detail for an attribution?
That said, I do admit that the coin is not in the best condition, and the photos suck...
17x15 mm, 2.42 grams.
For the record, I don't think any major design elements got washed out in the photos; the flat areas really are
that flat (whether due to poor strike or complications from the hole - probably a bit of both).
[EDIT: attributed as Khanate of Khiva! changed title]
