Abbasid Coin [解決]

Hi, i need some help to understand the year of this Abbasid dirham.
Thank you for your help.
w= 2.74 g -------- d=24 mm

I believe the year is 166:

ست وستين ومئة

Would that fit?

Have you been able to read the mint?

Thank you for your feedback. I was in doubt with 161 to be honest, but i am not an expert of abbasid coinage.
I have found 2 coins in the catalog:

Following the description the firt one is from al-Basra and the second from Madinat al-Salam, but it seems to my eyes they are from the same mint... I am quite convinced mine is al-Muhammadiya.

Do you think is it right?

Yup ─ al-Muhammadiyyah does fit the script.

And you're right that the catalogue description is mistaken about the mint.
