Caracalla Silver Antoninianus RIC IV Caracalla 297D

Monetary Context and the Antoninianus

The introduction of the antoninianus in early AD 215 represented one of the most consequential monetary reforms of the middle Roman Empire. Under Caracalla, the Roman imperial treasury faced severe structural deficits caused by massive pay increases granted to the legionaries, lavish military donatives, and expansive defensive and offensive operations along the northern and eastern frontiers. To expand the circulating money supply without possessing sufficient bullion reserves, Caracalla established this new silver coin, known in modern numismatic literature as the antoninianus after his official imperial name, Marcus Aurelius Antoninus. The ancient designation for this specific piece remains unrecorded, though contemporary administrative terminology likely termed it a double denarius or radiate piece. The newly issued coin was tariffed at a face value of two standard denarii, yet its physical silver content failed to match this nominal worth. While two contemporary denarii contained roughly 6.0 to 6.2 grams of an alloy that was approximately fifty to fifty-five percent silver, the early antoninianus was struck at an average weight of roughly 5.0 to 5.3 grams with a comparable or slightly lower fineness. By overvaluing the antoninianus by approximately twenty to twenty-five percent relative to its intrinsic bullion content, the imperial administration achieved a significant fiscal profit on reminted bullion. By AD 217, when RIC IV Caracalla 297D was struck, this fiscal mechanism was deeply integrated into military dispatches and state expenditures, creating inflationary tendencies and shifting hoard patterns throughout the Mediterranean.

Production Standards and the Rome Mint

The production of RIC IV Caracalla 297D was executed entirely at the principal imperial mint in Rome. During the Severan period, the Rome mint was structured into distinct workshops or officinae, each managed by imperial freedmen and staffed by specialized engravers, flan-casters, and moneyers. The alloy utilized for this issue was struck according to the debased Severan silver standard, which typically ranged between forty-eight and fifty-two percent fine silver, with the remainder composed of copper and small trace impurities. Blank flans were cast in open ceramic or bronze moulds and adjusted mechanically before being placed between hardened bronze or iron dies. Striking was performed by hand with heavy hammers, often generating slightly irregular flan edges, minor eccentricities in striking alignment, and die cracks along the perimeters. The mint at Rome operated under tight administrative supervision to ensure the timely delivery of newly dated coinage bearing the emperor's updated imperial titles for distribution to provincial treasuries and military headquarters. Although Caracalla was personally campaigning in the Roman East in AD 217, the metropolitan mint maintained regular annual output, coordinating closely with central directives to reflect both the emperor's ongoing military endeavors and his administrative anniversaries.

Obverse Iconography and Imperial Portraiture

The obverse of RIC IV Caracalla 297D displays the mature portrait of Caracalla facing right, wearing a radiate crown with both drapery and a military cuirass visible at the truncation of the bust. The radiate crown served as the primary diagnostic attribute indicating the double-denomination status of the coin, directly adopting the visual convention established for the bronze dupondius during the early Principate. In contrast to the laurel wreath reserved for standard denarii, the solar rays emerging from the imperial crown subtly associated the ruler with the celestial qualities of Sol Invictus, an ideological alignment that gained heightened prominence under the Severan dynasty. By AD 217, the stylistic rendering of Caracalla's portrait had evolved substantially from his youthful likenesses. Engravers at Rome depicted him with a rugged, furrowed brow, an intensely focused scowl, and a closely cropped military beard and hair. This aggressive stylistic shift was deliberately calculated to broadcast the image of a resolute soldier-emperor who shared the physical hardships of the rank and file. The addition of the military cuirass beneath the imperial drapery further emphasized his command over the legions during an active theater of war in the East.

Reverse Design: Victory, Captives, and Vota

The reverse design of RIC IV Caracalla 297D presents a dense and complex allegorical composition centered on imperial triumph and institutional continuity. The personification of Victory (Victoria) is depicted winged and draped, seated toward the right upon a mound of captured military spoils, which prominently include an armored cuirass and defensive shields. She balances a round shield on her knees, supporting it with her left hand as she displays or records an inscription reading VOT XX. Positioned directly in front of Victory is an erect military trophy composed of captured weapons, armor, and standards, at the foot of which sit two bound captives in attitudes of defeat and submission. This rich visual program fulfilled a dual political function. First, the trophy and captives celebrated Roman supremacy over foreign adversaries, directly invoking the ongoing hostilities against the Parthian Empire and celebrating prior victories over Germanic confederations. Second, the shield inscription VOT XX signified the imperial vota, referencing the solemn vows taken for the completion of twenty years of rule (vota soluta) and the anticipation of future longevity (vota suscepta). By uniting martial conquest with the ritual renewal of imperial authority, the mint provided divine sanction for Caracalla's continuous command.

Epigraphy and Titulature

The inscriptions found on RIC IV Caracalla 297D furnish precise epigraphic evidence regarding imperial titulature and dating. The obverse legend reads ANTONINVS PIVS AVG GERM, expanding to Antoninus Pius Augustus Germanicus. The cognomen Germanicus was officially assumed by Caracalla in AD 213 following his military campaigns along the Rhine and Danube frontiers, retaining a permanent place in his official styling. The epithet Pius reflects the traditional Antonine virtues of piety and familial loyalty that the Severans claimed through their fictitious adoption into the Antonine lineage. The reverse legend reads P M TR P XX COS IIII P P, expanding to Pontifex Maximus, Tribunicia Potestate XX, Consul IIII, Pater Patriae. The reference to the twentieth tribunician power securely anchors the issue to the year AD 217, as Caracalla's tribunician tenure was renewed annually on December 10, beginning in late AD 197. His fourth consulship, assumed in AD 213, remained unchanged until his death. Finally, the secondary legend VOT XX engraved on the reverse shield corresponds to the twentieth anniversary vows, completing a highly formal administrative statement that balanced civilian, military, and sacred offices.

Typology and Chronological Classification

Within the numismatic framework established in The Roman Imperial Coinage, type 297 represents the reverse design featuring Victory seated right with a trophy and captives, paired with the dated formula TR P XX. Sub-classification 297D is specifically distinguished by the exact treatment of the imperial bust on the obverse, requiring the bust to be radiate, draped, and cuirassed when viewed from the right. Other catalogued variations within the broader RIC 297 category exhibit differences in bust drapery, bare necklines, or alternate orientations, reflecting concurrent die engraving practices within the workshops of the Rome mint. Because Caracalla entered his twentieth tribunician year in December 216 and was assassinated near Carrhae on April 8, 217, the striking window for RIC IV Caracalla 297D was remarkably brief, spanning at most approximately four months. This issue therefore marks the terminal series of Caracalla's antoniniani. Following his death, his successor Macrinus temporarily suspended the striking of the denomination, rendering the AD 217 issues of Caracalla the final representatives of the first wave of double denarii.

Circulation, Hoards, and Economic Impact

The circulation of Caracalla's antoniniani was shaped by economic frictions arising from their artificial tariffing. Because the coins were overvalued in relation to their metallic silver content, the public exhibited a natural tendency to hoard older, finer denarii, an empirical manifestation of Gresham's Law. Nevertheless, antoniniani of AD 217 circulated widely alongside traditional denarii, particularly throughout military zones in the western provinces and the Danubian frontier, as well as in the eastern logistics hubs supporting the Parthian expedition. Hoard evidence from Britain, Gaul, the Balkans, and Syria demonstrates that antoniniani from the AD 215 to 217 issues were retained in long-term circulation, frequently surviving in hoards deposited during the mid-third century. The denomination proved unpopular with private merchants and civic populations due to its implicit tariff penalty, which prompted Macrinus and later Severus Alexander to curtail and eventually cease its regular production. It was not until the monetary crisis under Balbinus, Pupienus, and Gordian III in AD 238 that the radiate coin was revived as the primary silver denomination of the empire, at which point early pieces like RIC IV Caracalla 297D remained active in mixed currency pools.
