Sestertius - Hadrian COS III S C, Roma

Hadrian's COS III issues mark his third consulship, held from 119 AD onward — but the 126–127 dating places this piece within the period of his extensive provincial tours, during which he personally inspected frontier defenses, reformed military discipline, and, notably, ordered the construction of what would become his eponymous wall in Britain. The Roma type on the sestertius carried pointed political weight at a moment when Hadrian was conspicuously absent from the capital for years at a stretch, projecting Roman permanence while the emperor himself was rarely in Rome.
