Antoninianus of Carus

The antoninianus of Carus is a small bronze coin struck during the brief reign of Marcus Aurelius Carus, Roman emperor from 282 to 283 AD. By this late date the antoninianus, once a silver double-denarius, had become an essentially bronze coin carrying only a thin silver wash, so surviving examples are usually brown or dark in color rather than bright.

The coin shown here follows the standard pattern of the reign: a bearded, mature imperial head wearing the radiate (spiked) crown on the obverse, paired with a standing deity or personification on the reverse. Coins of Carus were produced across several imperial mints during his short rule and are a familiar type from the late-third-century recovery of the empire.

Carus was an experienced officer and Praetorian prefect who was proclaimed emperor in 282 AD after the death of Probus. He was already an older man at his accession, which is reflected in the mature, bearded portraits on his coinage, and he quickly raised his two sons, Carinus and Numerian, to share imperial authority.

His reign lasted barely a year: after campaigning successfully against the Sasanian Persians he died in 283 AD, according to ancient tradition struck by lightning. Because the reign was so short, his coinage was struck within a compressed window, yet the antoninianus remained the everyday coin of the period. By this era the denomination was a reformed radiate bronze, part of the monetary system stabilized under Aurelian a decade earlier, and coinage continued under his sons after his death.

Look first for the radiate crown of pointed spikes on the obverse, which marks the coin as a radiate antoninianus. The portrait is a mature, bearded man facing right, usually draped and cuirassed, surrounded by a Latin legend built around the name CARVS, commonly a form of IMP C M AVR CARVS P F AVG or IMP CARVS P F AVG.

The reverse typically shows a single standing deity or personification, such as Pax, Providentia, Aequitas, Salus, Felicitas, or Victoria, identified by the objects it holds (a branch, cornucopia, patera, wand, or scales) and named in the surrounding legend. Typical coins measure roughly 20-23 mm across and weigh about 3-4.5 grams. Many carry a mint mark in the lower reverse field or exergue that records the striking mint and workshop.

The antoninianus of Carus is an affordable ancient Roman coin, reflecting its bronze fabric and the large output of the late third century. Worn but identifiable examples trade at modest prices, while coins that retain sharp detail, a full legible legend, and traces of the original silvering command a clear premium.

Value is driven mainly by condition and eye appeal rather than rarity, since the common reverse types survive in quantity. Because Carus reigned for only about a year, his coins are somewhat scarcer than those of longer-reigning contemporaries, so an attractive, well-centered specimen with surviving silver wash can be more desirable than the low base price for the type suggests.
