AY K M AYR CEOY ALEXANDROC, laureate, draped bust right.
EP AGAQHFOROY ARX TABALEWN, horseman, radiate, on 
horseback pacing right, chlamys flying out behind, holding bipennis over left shoulder.

Mionnet Supp. VII, 550 (rev. decription corrected); Waddington 5303 (ditto); Paris 1381.

Mionnet and Waddington describe the reverse as the
emperor on horseback holding spear. A close examination
of the coin, however, shows the head of the bipennis and
the spikes of the rider's crown.
