Sestertius - Hadrian // DISCIPLINA AVG S C

The DISCIPLINA AVG coinage of Hadrian reflects his systematic overhaul of military training standards following his accession — he famously toured provincial garrisons in person, eating field rations with the troops and publicly rebuking officers whose units fell below his standards. The reverses of this series were almost certainly tied to that campaign of military reform, issuing alongside related types celebrating the army, the fleet, and individual provincial legions during the 120s and early 130s.

RIC II.3 1914 places this issue within Hadrian's later coinage, after the consolidation of his provincial tour program.
