Antoninianus of Salonina

The antoninianus of Salonina is a Roman billon coin struck for Cornelia Salonina, wife of the emperor Gallienus and mother of his heirs. As an empress (Augusta), her portrait appears on the standard silver-denomination antoninianus of the mid-third century, valued at two denarii and produced in large quantities to pay soldiers and fund the state.

The example shown here follows the usual pattern for an imperial woman's antoninianus: a draped female bust wearing a diadem on the obverse, paired with a single standing draped figure, a deity or personification, on the reverse. By the 250s AD the coin's silver had been heavily debased, so surviving pieces are best described as billon rather than good silver.

Salonina was married to Gallienus, who ruled jointly with his father Valerian from 253 AD and then alone until 268 AD. She was raised to the rank of Augusta and appears on the coinage throughout the reign, her issues emphasizing dynastic virtues such as concord, piety, fertility, and the security of the imperial house.

The years around 256-257 AD fell within a period of severe military and financial pressure on the empire, with frontier wars and mounting inflation. To meet the cost, the antoninianus was struck in enormous numbers from an increasingly base alloy, so coins of this era typically carry only a thin surface silvering over a copper-rich core. Salonina's coinage was issued from several mints active under Gallienus and continued until her death near the end of his reign.

Look first for a female portrait on the obverse: a draped bust facing right wearing a diadem or stephane, with the hair drawn back. On antoniniani of empresses the bust characteristically rests on a crescent, and the encircling Latin legend commonly reads a form of SALONINA AVG or CORNELIA SALONINA AVG. This female titulature, rather than an emperor's name, is the key attribution point.

The reverse typically shows a single standing draped figure, a deity or personification such as Venus, Juno, Pietas, Concordia, or Fecunditas, identified by attributes (a scepter, patera, apple, or child) and named in the surrounding legend. Typical coins measure roughly 20-23 mm in diameter and weigh about 2.5-4 grams, and the surface often shows patchy or worn silvering over a darker core.

The antoninianus of Salonina is a relatively common and affordable ancient Roman coin. Worn but clearly identifiable examples trade at modest prices, while pieces with a sharp portrait, complete legends, and surviving original silvering command a premium.

Value is driven mainly by condition, the clarity and appeal of the reverse type, and eye appeal rather than outright rarity, since most of her reverse types survive in quantity. Scarcer reverse legends, unusually high grade, or attractive intact silvering can lift the price well above that of ordinary circulated specimens.
