Help Identifying an Islamic Coin (3.1 cm Diameter) [solved]

I need help identifying an Islamic coin that I recently acquired. Here are the details:

• Diameter: 3.1 cm

• Material: bronze

I would greatly appreciate any insights regarding its origin, time period, and possible ruler. I am also interested in any translation of the inscriptions.

Thank you in advance for your expertise!

Quick reply for now:

1 — The obverse inscription is the usual statement: “There is no god but Allah; Muhammad is the prophet of Allah”.

2 — The reverse inscription is: “In the name of Allah, struck in ____ … …”

The name of the city could be retrieved by comparing it to a list of mints; IMO it starts “al-Kh…” or “al-H…” or “al-J…”. On early Islamic coins they don't write the diacritics, so the same shape could be up to 3 or 4 different letters. Only context tells you…

EDIT — This is followed by the year of issue … spelled out as usual. It seems to start with “75” (khamsa wa sab3in, i.e. 5 and 70) but the hundreds, which should follow, are quite enigmatic to me.
