Turkic Tribes. Ca 1092-1181 AD. AE Tetarteron 21mm, 3.21 gm. Imitating a post-reform issue of Alexius I. Crowned facing bust, wearing loros, holding cross-tipped sceptre and cross on globe. Jewelled cross with X at center and F C M D in the four corners, clockwise from top left. Cf. DOC IV 40a.20; cf. SB 1931. Good VF, brown patina with patches of green. A close approximation of the Byzantine prototype, most likely struck by one of the Turkish tribes that occupied Asia Minor and were pressing in upon the Byzantine heartland. The Seljuq Turks were aggressive in expanding their territory, but Alexius was effective in beating them back from the frontiers, only to see them supplanted by the Ottoman Turks, a much greater threat.
