TULUNID: Ahmad b. Tulun, 868-884, AE fals (3.45g), Thughur (al-Shamiya), AH(2)64, A-663.3, citing the caliph al-Mu'tamid (AH256-279), rare mint on the Cilician border of the Tulunid territory, VF, RRR. Very clear date, and certainly one of the finest known examples of this type, which is always rather primitively cast.
