Dear fellow members,

A french fellow would like the ID of a gold coin he has; 1.16 grams, 17mm diameter, picture on the french post:

Many thanks, Numisquare, your help is great,

Hi

I dont have references, but from reading the name on the coin, identification seems correct

The above comment is almost correct but not fully, my comments bellow:

PS: what's noted above as obverse, is basically the pic on the right; which i believe should be the reverse, as to keep ruler name on obverse

right pic
center: all correct
segments: all correct except top line
امنت بالله
I believed in God (Allah)

left pic
center: correct
reverse segments:
?الامير الا
ابو عبد ??
الله محمد بن
الامير ابي

Emir ??
?? Abu Abd
Allah Mohamad bin
Emir abi

the segments should be read first before the center, as the center part is continuation of the grand emir name

Thank you, Amer, for your comments. I have edited my post to change the first line of the obverse segment that was obviously incorrect.

The designation of obverse and reverse changes from place to place. For Ottoman coins the obverse is always the ruler's name / tughra. For medieval Islamic coins of North Africa, the obverse is designated as the side having religious phrases such as the kalima / shahadah, and the reverse side as having the ruler's name or date or other items.

Gentlemen,

I have to admit that your knowledge is great.
I downloaded the Hazard "Numismatic history of late medieval North Africa". I have been cooled at once by its 559 pages !

Thanks for your commitment,

Unless anyone wants to add a comment, I consider this issue as solved.
