Dirham Al-Mahdi(?)

Hi!

I have a piece of dirham which I bought years ago from auction.  The main issue is that I have lost the previous owners information notes and no matter how hard I try to “read” and compare this coin for other examples I cant really identify it…. Can someone recognice the date and mint etc?

I would be very thankfull. Even I know that there is a piece missing I think the date could be somehow readable?

Ps. Sorry, somehow I had big issues to add photos on this messages but eventually I was able to add them in very crappy way….

Images cut and rotated:

Thank you! I really hope somebody could help me with this one.

If memory serves, the important parts of the coin are the marginal of the obverse, where the mint should be at 6 hour and the date betwen 5 an 1 hours:

And the central part of the reverse, that contains the name of the caliph:


This is quite a useful site to start ID dirhams: https://islamiccoins.ancients.info/abbasid/ABBASID_CALIPHS.htm and https://islamiccoins.ancients.info/abbasid/almahdi.htm

And of course, there are a couple of hundred al-Mahdi dirhams on Zeno, that can help too.

That's exactly right. It means that we don't have the mint and, on top, what's left of the legends is flattened (as often) so difficult to read.

My best educated guess is that it reads: 

In the name of Allah this dirham was struck in _______ in the year one hundred and sixty.

The plain text is part of the missing legend. In bold the words you can see on the coin; in bold underlined the words you can see but are not easy to read, though “one hundred” is certain (مئة).

I'm uncertain of “sixty” (ستين) because there's something before that is very unclear, but too short to be a unit (i.e. one to nine). Could it be “ninety” (تسعين) instead of sixty??

Thank you very much, both of you!! I also made a conclusion that it is flattened, and that's why I found it to be a nightmare (for me) to read it. When I compare this to my other 3 dirhams the difference is clear, those other ones are much more easy to read (when you know what to look) and because with them I have all the informations saved and writed down. Now I have at least some kind of good quess for the date, and I can also check those links.

Ps. Apparently this Dirham has belonged to Beatrice Granberg (1916-2000) according to the  notes which I lost. Unfortunatly there is only a Finnish and Swedish wikipedia page for her. (I'm a Finnish speaker) But basicly she was expert of Islamic coins….
