I believe I posted this in 2018 and didn't get very far with it. I have now managed to figure out the basics, but there doesn't seem to be much more information online. I'm hoping someone here might have Treadwell's book on Buyid coinage.


The date appears to be of 379 (AD 989/990), but I can't read the mint.
Note the similarities to this coin:

Mine also has an extra line of text on the reverse and is 54% heavier (6.296 g) than the dirham I linked to- I wonder if it's a double dirham or just a crude planchet?
