Tacitus Silver Antoninianus RIC V Tacitus 82

Monetary Context and Aurelianic Heritage

The coinage of Marcus Claudius Tacitus operated entirely within the reformed monetary framework established by his predecessor Aurelian in 274 AD. Under Aurelian's reform, the radiate antoninianus, sometimes referred to modernly as the aurelianianus, was re-tariffed and standardized to contain approximately five percent silver, often represented by the Greek numeral mark of value XX.I or KA indicating twenty parts bronze to one part silver. Although RIC V Tacitus 82 frequently appears without an explicit mark of value on the reverse, its metrological profile and billon alloy directly align with this newly established post-reform standard. The accession of Tacitus in late 275 AD followed an interregnum after the assassination of Aurelian. The newly acclaimed emperor needed to maintain uninterrupted military payments and civil confidence. By continuing to strike radiate antoniniani with established weights of approximately 3.5 to 4.2 grams and a silver wash over a base bronze core, the imperial administration preserved the purchasing power and acceptance of base metal coinage throughout the western and central provinces.

Production and the Rome Mint

RIC V Tacitus 82 was struck exclusively at the imperial mint in Rome. During the reign of Tacitus, the Rome mint was organized into multiple distinct officinae or workshops, traditionally numbered or identified by Greek numerals, Roman numerals, or letters in the exergue or field. Production at Rome under Tacitus was characterized by rapid output, as the administration sought to disseminate portraiture of the new ruler to troops and municipal administrations across the Italian peninsula and neighboring dioceses. Blanks were cast in a low-grade copper-silver alloy and subjected to surface enrichment, a chemical blanching process that leached base copper from the outer surface prior to striking, producing a fleeting silver sheen that wore away quickly in daily circulation. Dies were cut by seasoned engravers who transitioned smoothly from the harsh, stylized likenesses of Aurelian to the softer, more elderly features traditionally associated with Tacitus.

Obverse Iconography and Bust Styles

The obverse of RIC V Tacitus 82 displays the radiate bust of Marcus Claudius Tacitus. The radiate crown remains the defining iconographic marker of the double-denar or antoninianus denomination since its introduction under Caracalla in 215 AD. Engravers at Rome rendered Tacitus with a prominent, slightly aquiline nose, neatly trimmed beard, and furrowed brow, conveying senatorial dignity and mature gravitas. Scholarly corpora record four distinct bust variants for this specific catalogue entry: radiate, draped, right; radiate, draped and cuirassed, right; radiate, cuirassed, right; and a scarcer martial bust facing left, radiate, holding a spear in the right hand and a shield on the left arm. These variations reflect the contemporary practice of die-cutters utilizing diverse dress conventions across multiple active officinae rather than representing chronological divisions within the brief issue.

Reverse Design: Aequitas and Imperial Equity

The reverse of the type depicts Aequitas, the Roman personification of equity, fair distribution, and honest measurement. She is portrayed draped, standing and facing left, holding a pair of balance scales in her outstretched right hand and cradling a cornucopiae, the horn of plenty, in her left arm. In imperial numismatics, the balance scales symbolized exact weight and fair exchange, particularly in the distribution of grain allotments, military pay, and the reliable composition of minted money. The cornucopiae emphasized the abundance and agricultural prosperity that flowed from honest imperial administration. For an emperor elevated by the Senate amidst economic uncertainty, deploying Aequitas served as a direct ideological guarantee to the army and civilian population that the treasury would honor its financial obligations honestly and without debasing the currency.

Inscriptions and Epigraphic Analysis

The obverse legend of RIC V Tacitus 82 reads IMP C M CL TACITVS AVG, expanding to Imperator Caesar Marcus Claudius Tacitus Augustus. This standard imperial titulature invokes the supreme military command (Imperator), the dynastic prestige of the early principate (Caesar), the ruler's full tria nomina, and the venerable title Augustus. On the reverse, the legend AEQVITAS AVG abbreviates Aequitas Augusti, translating as 'the Equity of the Emperor.' The lettering is executed in the standard late third-century capital script characteristic of the Rome mint, with compact, sharply serifed letters. Depending on the workshop emission, the exergue may be plain or bear officina marks, though the type definition in RIC encompasses specimens where the primary field elements and legend formulation remain invariant.

Typology and Relative Chronology

Within the typology established by Percy H. Webb in Roman Imperial Coinage and refined by Sylviane Estiot, RIC V Tacitus 82 is situated within the earliest Rome mint issues for the emperor, struck late in 275 AD and extending into early 276 AD. It belongs to a thematic series from Rome celebrating traditional civic and administrative virtues, alongside complementary issues for Fides Militum, Pax Publica, and Providencia. Because Tacitus was active as emperor for only six to seven months, dying on campaign in Asia Minor in mid-276 AD, issues of this type represent a tightly bounded chronological horizon. The multi-bust typology of RIC 82 demonstrates that the Rome mint rapidly mobilized all its facilities to produce antoniniani in high volume from the very beginning of the reign.

Circulation Patterns and Hoard Contexts

Coins of RIC V Tacitus 82 circulated primarily within Italy and the western provinces, though hoard evidence demonstrates movement throughout the Roman Mediterranean. Base billon radiates of Tacitus regularly appear in large late third-century coin hoards, such as the Cunetio and Normanby hoards from Britain, the Eauze hoard from Gaul, and various Italian and Balkan finds. In these deposits, issues of Tacitus consistently form a small percentage of the total contents, reflecting both the brevity of his reign and the massive volume of surviving coinage from Gallienus, Claudius II, and Aurelian. Because these coins maintained Aurelian's reformed billon standard, they remained in circulation through the reigns of Florian, Probus, and Carus, continuing to pass as standard currency until the radical monetary reforms of Diocletian in 294 AD demonetized the pre-reform radiate denominations.
