Denarius - Trajan COS V P P S P Q R OPTIMO PRINC VESTA, Vesta

Trajan's fifth consulship, held from 103 AD, anchored a prolonged series of issues bearing the COS V titulature that continued well past the Dacian wars. The OPTIMO PRINC epithet — "best ruler" — was formally voted to Trajan by the Senate around 114 AD, though it appears on coins throughout this broader window, making precise dating within the type genuinely difficult. Vesta's inclusion reflects the intense religious conservatism of Trajanic coinage policy, deliberately evoking traditional Roman piety at a moment when the empire's military ambitions were anything but conservative.
