Julia Mamaea Silver Denarius, RIC IV Severus Alexander 335

Monetary Context and the Severan Denarius

During the reign of Severus Alexander (222 to 235 AD), the silver denarius remained the cornerstone of the Roman imperial monetary economy, despite persistent inflationary pressures and fiscal strain inherited from the reigns of Caracalla and Elagabalus. Caracalla had previously introduced the double denarius, or antoninianus, around 215 AD to alleviate bullion deficits, but production of that larger denomination ceased under Elagabalus and Severus Alexander, making the traditional denarius once again the sole primary silver coin issued by the state. Metallurgical examinations across modern corpora indicate that the denarius during Severus Alexander's administration experienced a modest stabilization in silver purity, hovering generally between 40 and 45 percent fine silver, paired with an intentional alloy of copper. This stable baseline enabled the imperial administration to maintain standard state operations, disburse annual military stipends, and fund administrative costs across the provinces. Within this framework, issues struck for imperial women served a dual fiscal and ideological purpose. By producing sizable quantities of denarii under the name and image of Julia Mamaea, the administration integrated dynastic legitimization directly into the primary transactional currency of the empire, ensuring widespread visual contact with the imperial family across regional marketplaces and legionary camps.

Production Standards and Mint Attribution

The entire attested production run of RIC IV Severus Alexander 335 is assigned securely to the imperial mint of Rome. Unlike during early Severan times when auxiliary mints operated at Antioch or auxiliary eastern workshops struck silver, the minting of standard denarii under Severus Alexander was centralized in Rome, with a possible secondary or temporary eastern facility operating early in his reign. The mint at Rome operated with distinct officinae or workshops responsible for coordinating die engraving, flan casting, and striking across the various substantive issues. For RIC 335, production followed traditional hot-striking techniques, where cast silver flans were placed between lower obverse anvil dies and upper reverse punch dies. Individual weights of preserved specimens generally conform to the Severan standard, typically falling between 2.7 and 3.4 grams, with a central cluster around 3.0 to 3.1 grams and flan diameters spanning 18 to 21 millimeters. Because flans were cast individually and often adjusted with shears, weight variations among genuine pieces are common, though significant clustering indicates strict batch control by mint magistrates. Axis orientations are predominantly vertical or near-vertical, reflecting the regularized administrative control typical of the centralized mint of Rome in the 220s and early 230s AD.

Obverse Iconography and Imperial Representation

The obverse of RIC 335 is dominated by the draped bust of Julia Mamaea facing right, adorned with a crescent-shaped diadem or stephane set upon an intricate imperial hairstyle. The portraiture is characteristic of Severan court art, departing from the youthful, stylized depictions of early Severan dynastic women toward a mature, sober representation that visually supported her maternal and regnal authority. Her hair is rendered in undulating waves brushed horizontally across the head and gathered into a broad, flat plait or bun turned upward against the nape of the neck, an elaborate coiffure carefully documented across Severan sculptural and glyptic portrait traditions. The diadem signifies her exalted imperial status as Augusta, a designation emphasized by the accompanying legend. Drapes wrap smoothly over the shoulders, terminating neatly above the beaded border. Die studies reveal subtle variation in portrait modeling across different die engravers at the Rome mint, ranging from refined, high-relief classical profiles to flatter, slightly more compact depictions produced during later working phases.

Reverse Iconography: Felicitas and the Column

The reverse iconography of RIC 335 depicts the goddess Felicitas standing draped, facing front with her head turned to the left. Her posture is deliberately relaxed and languid, depicted with her legs crossed at the ankles. In her right hand, she elevates a caduceus, the traditional winged wand associated with trade, peace, and auspicious fortune, while her left arm rests casually on a short architectural column. The leaning posture against a column was an established visual trope in Roman imperial numismatics, originally borrowed from Hellenistic prototypes to denote enduring stability, permanence, and effortless security (securitas). By synthesizing this posture with Felicitas, the designers presented public welfare and happiness not as a fleeting condition, but as a deeply rooted, unshakeable state underpinned by the Severan regime. Drapery folds fall gracefully down her limbs, articulating the stance without obscuring the structural form of the supporting pillar. The arrangement balances the circular field inside the beaded rim, maintaining clarity even on slightly off-center flans.

Epigraphy and Legend Structure

The inscriptions on RIC 335 are concise, unpunctuated, and composed in classic imperial Roman capitals. The obverse legend reads IVLIA MAMAEA AVG, beginning on the lower left and continuing clockwise uninterrupted or separated slightly above the bust. This legend identifies the Augusta by her primary family names and honors, omitting extensive titulature in favor of direct, immediate recognition. On the reverse, the inscription FELICITAS PVBLICA runs clockwise along the circumference, translating directly to 'Public Felicity' or 'The Happiness of the Public.' The epigraphy features standard Severan lettering: tall, slender letterforms with modest serifs on the vertical strokes. Ligatures are absent on standard issues of this type. Minor die variations exist in letter spacing and the precise positioning of the legend relative to the attributes of Felicitas, such as whether the caduceus breaks the inscription between letters or remains entirely enclosed within the inner field. Together, the legends combine personal imperial prestige with an enduring civic virtue, aligning the maternal ruler directly with the material and moral wellbeing of the Roman citizenry.

Typology and Chronological Classification

Within the framework of Roman Imperial Coinage Volume IV Part 2, type 335 is categorized under the coinage struck for Julia Mamaea under the administrative authority of Severus Alexander. Harold Mattingly and Edward A. Sydenham established a broad production timeframe spanning roughly 225 to 235 AD, reflecting the core period of Mamaea's active public primacy following the dismissal of Julia Maesa and extending to the end of the dynasty. While Severus Alexander's own coins frequently carry tribunician dates permitting year-by-year chronological precision, the parallel issues struck for the Augustae lack explicit tribunician counters and must be dated typologically through hoard distribution, portrait development, and stylistic parallels with datable imperial obverses. RIC 335 is typologically distinct from several neighboring issues honoring Felicitas. For example, RIC 336 portrays Felicitas holding a patera or caduceus while seated, while other varieties feature her standing erect without the supportive column. RIC 335 specifically isolates the standing, column-leaning variant paired with the unadorned obverse legend IVLIA MAMAEA AVG, distinguishing it from subsequent fourth-phase Severan issues or provincial bronzes bearing Greek legends.

Circulation, Hoard Context, and Survival

RIC IV Severus Alexander 335 circulated extensively across the Western, Balkan, and Eastern provinces of the empire. Excavation and hoard reports demonstrate that Severan denarii remained heavily active in commercial transactions well into the middle of the third century AD, continuing to change hands alongside the debased double denarii issued by the Gordians, Philip I, and Decius. Because the silver fineness of denarii from Severus Alexander's reign was significantly higher than the billon and bronze-alloyed coinages issued after 250 AD, Gresham's law encouraged the hoarding and withdrawal of these issues during the monetary debasements of the mid-250s and 260s AD. As a result, RIC 335 appears consistently in mid-century deposits, such as the major Romano-British hoards, Rhine frontier military caches, and Balkan hoards buried during Gothic incursions. The high volume of surviving specimens across global public and private collections confirms that this was not a ceremonial emission, but an abundant, workaday silver coin that saw prolonged utility in military and regional markets across the Roman world.
