But I couldn't find this coin in the catalog at Tunisia.
My mistake. I only looked till the start of the decimal system and this coin was one of the first since then. The decimal system started in the course of AH 1308, I looked in the former system till AH 1308, the date on the coin, and there I couldn't find it.
