Constantius I, as Caesar, 293-305, Argenteus

Constantius I, Argenteus, AR, as Caesar AD 293–305, struck c. AD 298–299; 3.44 g; 19 mm. Thessalonica mint. Obv. CONSTANTIVS NOB CAES; laureate head right. Rev. VIRTVS MILITVM; four‑turreted campgate with open doors; star above arch. Struck after Diocletian’s reform to the argenteus standard (c. 1/96 lb of silver), on the typical module of the early Tetrarchic series. RIC VI Thessalonica 12a. Introduced by Diocletian around AD 294, the argenteus restored a high-fineness silver denomination intended to stabilize state payments, especially to the army. Constantius I, serving as Caesar under Maximian, oversaw key western campaigns, including the reconquest of Britain from the usurpers Carausius and Allectus. The VIRTVS MILITVM legend and campgate reverse broadcast the Tetrarchy’s emphasis on military discipline and fortified frontiers, while the standardized portrait style underlined the collegiate nature of imperial authority; Thessalonica’s output after 298 reflects the reorganized mint network supporting these policies in the Balkan region.
