I shiver to go where Manzikert dared no go. I think I see "zarb" in the central segment of the star, so I expect to see the mint name underneath. The characters there are not like anything in KM (as usual), but at least I can say that the mint name is short, like Meknes. It looks like Fes is too short and Fes Hazrat too long. It's easier for me to recognise Chinese characters on coins than Arabic characters. Odd.
