Roman Quinarius

The quinarius was a small silver denomination of ancient Rome, valued at half a denarius. It is one of the smaller silver coins of the Roman world, and surviving examples are notably tiny and light compared with the more familiar denarius. The piece shown here carries a helmeted head of Roma facing right on the obverse and a horse prancing right on the reverse.

On this example the obverse shows Roma wearing a Corinthian-style helmet with curled hair beneath, a classic personification of the city and its martial identity. The reverse horse is a common Roman coin motif tied to victory, cavalry, and imperial imagery. Because the quinarius was struck intermittently rather than continuously, individual issues can vary considerably in design, and any given piece is best read from its own obverse and reverse types rather than a single fixed pattern.

The quinarius originated in the Roman Republic as a silver coin marked with the numeral V, standing for five asses, exactly half the value of the denarius. Its production was never as steady as that of the denarius; it appeared in bursts, faded from use, and was periodically revived, so quinarii are far scarcer than the everyday denarius.

Under the Empire the silver quinarius continued as an occasional issue, often struck to mark specific events, reigns, or commemorations rather than as a mainstay of daily commerce. Reverse types drawn from Roman iconography, including figures of Victory and horses, recur across many of these issues. The example here, attributed to the 1st–2nd century AD, sits within this imperial-era tradition of small, sporadically minted silver.

Because the denomination was produced in comparatively limited numbers and over scattered periods, exact mintage figures are not recorded, and the historical picture is pieced together from surviving coins, hoards, and ancient references rather than from precise production records.

Size is the first clue: the quinarius is a small, light silver coin, roughly half the weight of a denarius, so a very small ancient silver piece is a strong starting point. The metal should read as silver, though ancient examples are often toned, patinated, or slightly debased in appearance.

On this coin, identify the obverse by the head of Roma facing right wearing a Corinthian-style helmet, with curled hair visible beneath the helmet. The reverse shows a horse prancing to the right. Look also for traces of Latin lettering, legends, or control marks in the fields and around the rim, which on quinarii can name authorities or carry the denomination mark; these are frequently worn or off-center on small ancient flans.

Ancient hand-struck coins like this are typically irregular in shape, with uneven borders and centering, and no two are identical. Weight, diameter, and the specific obverse and reverse types together are what pin down a quinarius versus a denarius or another small silver denomination.

Values for Roman silver quinarii vary widely with issue, condition, and the strength of the strike. As a scarcer denomination than the denarius, an identifiable, reasonably preserved silver quinarius commonly falls somewhere in the low tens to low hundreds of dollars, while worn, corroded, or poorly centered pieces sit at the lower end.

Exceptional examples with sharp detail, clear legends, attractive toning, and well-documented attribution to a specific issuer or reign can command higher prices, particularly for rarer types. Conversely, damage, tooling, smoothing, or heavy wear reduce value substantially.

Because ancient coins are actively forged, provenance and authentication weigh heavily on price. A quinarius accompanied by a credible attribution, dealer record, or third-party certification will generally be worth considerably more than an unattributed piece of similar apparent grade.
