Justinian I. 527-565. Æ 12 Nummi (15mm, 4.58 g, 1h). Alexandria mint. Diademed, draped, and cuirassed bust right / Cross between large IB; ΑΛΕΞ. DOC 274; MIBE 165; SB 247. VF, dark green patina, light smoothing.
Stylistically, this coin appears to be Justinian I, but without a clear obverse legend, it could also be attributed to Justin I (SB 112) or Justin II (SB 389).
