Quinarius Aureus - Hadrian COS III, Victory

The quinarius aureus — half the weight of a standard aureus — was never a workhorse of Roman commerce. Hadrian's issues in this denomination are theoretically tied to donative distributions, where precise fractional values mattered more than in general trade. The COS III dating places these firmly after 128 AD by some reckonings, though the tribunician evidence allows the slightly earlier window assigned here.

RIC II.3 797 is among the better-documented of Hadrian's gold quinarii, but surviving examples remain genuinely scarce.
