Aurelian Antoninianus, RIC V Aurelian 244

Monetary Context

The radiate antoninianus, originally introduced under Caracalla in AD 215 as a double denarius, suffered severe progressive debasement across the mid-third century AD. By the accession of Aurelian in late AD 270, the Roman monetary system was characterized by catastrophic hyperinflation and collapse of intrinsic silver content. Coinage struck during the preceding reigns of Gallienus and Claudius II Gothicus had plummeted to silver purities frequently below two to three percent, leaving circulating radiates as little more than bronze or potin blanks covered by an unstable silver wash. Aurelian prioritized military stabilization and monetary rehabilitation, culminating in his empire-wide currency reform around AD 274, which formalized the reformed radiate marked XXI or KA at a guaranteed five percent silver standard. RIC V Aurelian 244 belongs within the production framework of Siscia during this active transformative period of AD 270 to AD 275. The type was issued as billon currency intended to meet the heavy logistical payrolls demanded by Danubian legionaries defending the Illyrian frontier against Germanic incursions while preparing for the reintegration of the Palmyrene and Gallic breakaway regimes.

Production and Mints

All issues classified under RIC V Aurelian 244 were struck exclusively at the Siscia mint, located at modern Sisak, Croatia. Situated at the confluence of the Sava and Kupa rivers, Siscia occupied an exceptional strategic junction connecting Italy, the Balkans, and the Danubian limes. The mint had been established under Gallienus around AD 262 to provide direct fiscal liquidity to regional garrisons without relying solely on the strained mint at Rome. Aurelian expanded Siscia's operational capacity to multiple officinae, typically numbered or lettered in Latin or Greek. Production involved casting alloyed billon blanks containing roughly two to four percent silver, with trace amounts of tin, lead, and zinc balancing the predominant copper matrix. Blanks were subjected to surface depletion silvering, an acid-leaching process that removed base surface copper to create an artificial, lustrous silvery sheen when fresh. Dies were hand-engraved in the characteristic regional style of Siscia, notable for sharp, elongated portraiture, neat square lettering, and compact figurative modeling on the reverses.

Obverse Iconography and Variations

The obverse of RIC V Aurelian 244 portrays the emperor adorned with the radiate crown, the signature visual attribute of the antoninianus signaling its double tariff relative to the traditional denarius. In ancient Roman solar theology, the radiate crown equated the living ruler with the invictus solar deity Sol, an ideological identification that Aurelian elevated to imperial primacy. The catalogue type encompasses three recognized bust treatments that reflect standard workshop variability at Siscia: a radiate, draped bust facing right; a radiate, cuirassed bust facing right; and a less common radiate, cuirassed bust facing left. The right-facing cuirassed variant conveys Aurelian as an imperator in active field armor, emphasizing military preparedness, whereas the draped variant incorporates the paludamentum over the breastplate to highlight civil and administrative majesty. Left-facing portraits from Siscia often served an elevated ceremonial presentation within distinct production emissions.

Reverse Iconography and Composition

The reverse iconography of RIC V Aurelian 244 represents an explicit visual manifestation of political-military solidarity. Two standing figures occupy the field: the emperor stands on the left or center right, facing right, clad in military dress or imperial drapery and holding a staff or sceptre in his left hand, while clasping the right hand of Concordia, who stands facing left. Concordia, the personification of unity, harmony, and mutual fidelity, is typically depicted draped in a stola and palla, occasionally holding a sceptre or cornucopia in her left hand. The focal point of the composition is the dextrarum iunctio, the ceremonial clasping of right hands inherited from ancient Roman marriage and public treaty rituals. On this military issue, the gesture serves as a public declaration that the emperor and his armed forces stood in unbreakable concord, reassuring civilian populations and troop contingents alike of political stability following decades of violent military usurpations.

Epigraphy and Legend Structure

The obverse inscription of RIC V Aurelian 244 reads continuously as IMP C AVRELIANVS AVG, which expands epigraphically to Imperator Caesar Aurelianus Augustus. This standardized early-to-mid reign formula invokes the supreme military authority of Imperator, the dynastic mantle of Caesar, the personal gentilicium Aurelianus, and the sacred constitutional authority of Augustus. The reverse inscription carries the legend CONCORDIA MILITVM, translating directly as 'Harmony of the Soldiers.' This specific legend was one of the most prominent epigraphic slogans of the mid-third century crisis, serving as both an assertion of present army loyalty and a cautionary plea against mutiny. In the lower field or exergual compartment, workshop symbols and officina letters appear on varying emissions of the type, distinguishing the specific striking phases and production ateliers within the Siscia mint facility.

Typology and Chronological Sequence

Within Percy H. Webb's classic classification in Roman Imperial Coinage (RIC V.1), number 244 isolates Siscia's specific CONCORDIA MILITVM emission bearing the IMP C AVRELIANVS AVG obverse legend paired with the handshake scene between Aurelian and Concordia. Modern chronological studies, notably by Sylviane Estiot and the Corpus des monnaies de l'Empire romain, divide Aurelian's coinage at Siscia into successive phases: pre-reform emissions struck between late AD 270 and early AD 274, and reformed issues produced from AD 274 to late AD 275 that display standardized mark denominations such as XXI. RIC 244 encompasses emissions preceding and bridging into the monumental reform horizon, as evidenced by stylistic links in die carving, portrait progression, and varied control markings. The type is closely linked to neighboring Siscia issues depicting Sol, Victoria, and Mars, but is distinguished by its specific obverse-reverse legend combination and the two-figure dextrarum iunctio tableau.

Circulation and Archaeological Context

Coins of RIC V Aurelian 244 circulated widely throughout the military corridors of Pannonia, Moesia, and northern Italy, where troops regularly received newly minted billon radiates directly from Siscia. However, because of the sweeping reach of Aurelian's administrative campaigns, specimens also diffused into broader commercial channels across the western and eastern provinces. In archaeological contexts and hoards, such as large British, Gallic, and Danubian coin hoards buried during the late third and early fourth centuries, pre-reform and transitional antoniniani of Aurelian are found alongside older debased radiates of Gallienus, Claudius II, and the Gallic emperors. Following Aurelian's currency reform in AD 274 and the subsequent monetary restructuring by Diocletian in AD 294 to 296, earlier base radiates gradually lost their official purchasing power, suffering widespread demonetization, clandestine cutting, or return to state melting pots to furnish bullion for newer denominations.
