Denarius - Hadrian COS III •

Hadrian's third consulship, held from 119 AD, gave his coinage a reliable chronological anchor — issues bearing COS III without tribunician dating cluster tightly around 125–128, when Hadrian was returning from his first great provincial tour. He had spent years personally inspecting frontier defenses from Britain to Syria, and the mint at Rome was producing fresh coinage in his absence largely on the strength of established administrative routine rather than direct imperial oversight.

RIC II.3 #866 belongs to the revised Mattingly corpus, which substantially reorganized Hadrianic silver away from the older RIC II numbering — earlier catalog references for this type may not correspond cleanly.
