Constantius, as Caesar, AE Radiatus

Constantius I Chlorus, as Caesar, radiate nummus (AE radiatus), billon, AD 293–305, Cyzicus mint, 3.11 g, 20 mm. Obverse with radiate, draped and cuirassed bust of Constantius right; legend FL VAL CONSTANTIVS NOB CAES.

Issued during the Tetrarchic period after the reforms of Diocletian, this type belongs to the coinage produced for Constantius while he held the rank of Caesar, reflecting the new collegiate structure of imperial rule. The reverse legend CONCORDIA MILITVM emphasizes military unity and loyalty as a foundation of government, a recurring message in late third-century imperial propaganda amid frontier pressures and internal restructuring. The Cyzicus mint, active in supplying the eastern provinces, contributed substantially to the standardized output that characterized Tetrarchic monetary administration.
