Severus Alexander Silver Denarius, RIC IV Severus Alexander 45

Monetary Context and Imperial Policy

The monetary system inherited by Severus Alexander in AD 222 had been severely disrupted by successive debasements under Septimius Severus, Caracalla, and Elagabalus. Caracalla had introduced the double denarius (antoninianus) in AD 215, which quickly created inflationary pressures due to its tariffed face value of two denarii against an intrinsic silver content of only about one and a half denarii. Under Severus Alexander, the imperial government temporarily suspended the production of the antoninianus and reverted exclusively to the traditional silver denarius as the primary precious-metal coin in regular circulation. This conservative reform was intended to restore public confidence in the standard currency, reflecting the wider senatorial influence that characterised Alexander's early administration. Denarii struck during this phase, including RIC IV Severus Alexander 45, adhered to an intrinsic silver standard stabilised between forty and forty-five percent fineness. While the denarius never returned to the high purity of the second century Antonine issues, Alexander's fiscal officials managed to maintain a predictable standard of mass and metal quality that facilitated internal commerce and met army payroll obligations without the immediate panic associated with previous monetary experiments.

Production Standards and Mint Operation

The entire production run of RIC IV Severus Alexander 45 took place at the primary imperial mint located in the city of Rome. The Rome mint was organised into several officinae (workshops), which shared the responsibility of striking gold, silver, and base metal denominations. During the early years of Severus Alexander's reign, the mint operated with remarkable consistency, utilizing circular flans prepared by casting individual metal pellets in open moulds before hot-striking between intaglio dies. The alloy used in AD 225 consisted of a copper-silver binary mix, frequently containing trace impurities of lead, bismuth, and gold typical of recycled Roman imperial bullion. Chemical surface enrichment, achieved by pickling the freshly cast blanks in an organic acid solution, created a thin microscopic veneer of pure silver that disguised the baser core upon initial distribution. The standard weight target for denarii of this issue centred around 3.0 to 3.2 grams, though surviving individual specimens vary between 2.6 and 3.5 grams due to manual blank adjustment al marco rather than individual piece weighing al pezzo. Die axes show a marked preference for a six o'clock (inverted) or twelve o'clock alignment, typical of the mechanical discipline of the metropolitan Roman mint.

Obverse Iconography and Imperial Portraiture

The obverse of RIC IV Severus Alexander 45 features an official right-facing portrait of the young prince, depicted as a mature youth. By AD 225, imperial die engravers had abandoned the juvenile, softer features of his earliest coins from AD 222, adopting a firmer, more authoritative jawline while preserving his youthful countenance. The emperor wears the laurel wreath (corona triumphalis), which serves as the traditional symbol of victorious command and divine protection. The wreath ties are depicted fluttering behind the nape of the neck. Across his shoulders and chest, the bust is draped with the paludamentum or civic mantle, neatly gathered with detailed fabric folds indicating high-status imperial costume. The execution of the hair follows the neat, short Severan style, carved with fine, stippled strokes rather than the elongated curls favoured by his immediate predecessor. The surrounding legend starts at the lower left and encircles the portrait continuously along the beaded border, framing the likeness in a dignified, orderly composition.

Reverse Iconography of Mars Ultor and Gradivus

The reverse iconography of RIC IV Severus Alexander 45 displays Mars, the Roman deity of war and mythical progenitor of the Roman people, in dynamic forward motion toward the right. Mars is depicted according to Hellenistic and classicising Roman conventions: heroically nude except for an elaborately crested helmet and a light military cloak (chlamys) that is pinned at the neck and flows backward in the wind behind his muscular torso. In his right hand, the deity carries a transverse spear pointed forward in an aggressive posture of march or assault, embodying the attributes of Mars Gradivus (the striding or advancing god). Balanced over his left shoulder, he bears a military trophy (tropaeum), consisting of captured armor, greaves, and shields mounted upon a wooden cruciform frame. This visual program conveyed military prowess, readiness, and divine favor to Roman soldiers and citizens alike, reinforcing the legitimacy of a prince who had no personal combat record. By adopting the vigorous imagery of Mars, the imperial court sought to reassure the legions of the emperor's martial virtues and loyalty to traditional Roman arms.

Inscriptions and Epigraphic Analysis

The epigraphy of RIC IV Severus Alexander 45 adheres to classical Roman conventions with precise abbreviation patterns. The obverse inscription reads IMP C M AVR SEV ALEXAND AVG, expanding in Latin to Imperator Caesar Marcus Aurelius Severus Alexander Augustus. The title Imperator functions as the military praenomen, Caesar and Marcus Aurelius connect him formally to the Antonine ancestral lineage claimed by the Severan house, Severus preserves his dynastic affinity with Septimius Severus, and Alexander identifies his personal imperial cognomen, culminating in the supreme rank of Augustus. The reverse inscription reads P M TR P IIII COS P P, which abbreviates Pontifex Maximus, Tribunicia Potestate IIII, Consul, Pater Patriae. The absence of a numerical suffix on COS indicates his first consulship, which had been celebrated in AD 222 alongside Elagabalus. The fourth renewal of the tribunician power (TR P IIII) provides the definitive chronological marker, while Pontifex Maximus and Pater Patriae record his supreme pontifical leadership and honorary status as father of his country.

Typology and Chronological Placement

Within the typology established by Harold Mattingly and Edward Sydenham in The Roman Imperial Coinage, type 45 is classified among the dated silver issues of Alexander's fourth tribunician year. Severus Alexander had been elevated to the rank of Caesar in AD 221 and succeeded to the purple in March AD 222, when he assumed his first tribunician power. The imperial administration customarily renewed the tribunician count each year on December 10 or January 1; consequently, TR P IIII corresponds specifically to the calendar year AD 225. Because Alexander did not enter his second consulship until January 1, AD 226 (at which point reverse legends changed to COS II), the unnumbered COS confirms that this type was struck exclusively in AD 225. The Mars Gradivus type appears in parallel on contemporary aureus and bronze denominations (such as sestertii and dupondii), demonstrating a cohesive thematic emission produced across multiple mint departments at Rome during this single administrative year.

Circulation Patterns and Hoard Evidence

Denarii of Severus Alexander dated to AD 225 circulated widely throughout the provinces of the Roman Empire and across frontier zones. Because Alexander's silver issues maintained a relatively stable alloy compared to the wild fluctuations under Caracalla and Elagabalus, they were readily accepted in civilian marketplaces and military encampments. Substantial quantities of this specific type have been recovered from major third-century hoards discovered in Britannia, Gaul, the Rhine frontier, the Danubian provinces, and northern Italy. In these hoards, denarii of Alexander commonly appear alongside earlier Antonine and Severan silver, circulating together for several decades. When the double denarius was reintroduced on an immense scale under Gordian III and Philip I in the late AD 230s and 240s, older denarii like RIC 45 were gradually sequestered, hoarded, or melted down for their silver content. However, numerous worn specimens in hoards buried during the Crisis of the Third Century reveal that many remained in active circulation as fractional silver down to the reign of Postumus and the Gallic Empire.
