Dupondius
Bronze / Brass (aes) · ~12.5g
23 BC – AD 268
Worth two asses, the dupondius was struck in orichalcum (brass) like the sestertius. Collectors distinguish it from the as by the radiate crown worn by the emperor on the obverse — a deliberate design choice to help users tell the two similarly-sized coins apart in daily use.
