Tetricus I Antoninianus RIC V Tetricus I 257

Monetary Context

The antoninianus designated as RIC V Tetricus I 257 belongs to the terminal stage of the Gallic Empire's monetary system. Initiated by Postumus in AD 260, the Gallic monetary regime initially sustained higher silver content than the central Roman issues of Gallienus. However, by the accession of Tetricus I in AD 271, rampant inflation and military expenditure had degraded the radiate denomination into a heavily debased alloy consisting predominantly of copper, tin, and lead with minimal silver content, often under two percent. This specific issue served the fiscal necessity of mass coin production while visually advertising the succession of Tetricus II, who had been elevated to the rank of Caesar. The pairing of dynastic succession with traditional priestly imagery was designed to inspire public confidence among civilian populations and legionary garrisons across Gaul and Britain during an era of acute political fragility.

Production and Mints

In the foundational fifth volume of Roman Imperial Coinage, Percy Webb distributed the coinages of the Tetrici across Cologne and an uncertain southern Gallic mint. Subsequent scholarship, led by numismatists such as Robert Drinkwater and Georges Depeyrot, has revised this spatial framework, demonstrating that the primary northern operation was located at Augusta Treverorum (Trier), with a secondary mint functioning either at Cologne or an undetermined southern center, sometimes proposed as Lugdunum (Lyon) or an itinerant field mint. Die analysis demonstrates that production of type 257 was carried out at tremendous speed. Flans were cast in mass-production moulds, resulting in irregular circumferences, ragged edges, and frequent striking off-center. Despite the low intrinsic silver content, the mints applied an artificial silver-enrichment wash or chemical surface treatment to give fresh strikes a bright appearance before rapid wear exposed the underlying copper alloy.

Obverse Design and Portraiture

The obverse of RIC V Tetricus I 257 presents the adolescent bust of the junior ruler Tetricus II. Numismatic records classify variations ranging from a radiate bust draped and cuirassed to an unpublished variant bust style recorded in modern corpora. Because the authority rested with his father, Tetricus I, the youth is presented in standard princely iconography, devoid of the mature bearded features of the senior Augustus. The style varies from carefully engraved portraits with fine facial contours and orderly drapery to highly stylized, schematic portraits executed by secondary die-engravers working under intense fiscal deadlines. As with many late Gallic radiate types, flan size is frequently smaller than the die diameter, causing segments of the head or border to extend beyond the coin rim.

Reverse Design and Iconography

The reverse iconography depicts traditional Roman pontifical implements, typically including the lituus (augur's wand), the urceus or gutturnium (sacrificial jug), the patera (libation dish), the simpulum (ritual ladle), and the aspergillum (sprinkler). This sacred imagery had long served on Roman imperial coinage to signal the entry of an imperial prince into the ancestral priestly colleges, affirming both moral rectitude and dynastic legitimacy. The arrangement of the vessels varies across different die pairings, with some dies rendering the utensils with precise detail while others reduce them to simplified linear outlines. Through these priestly symbols, the imperial court emphasized religious continuity and adherence to Roman traditions at a moment when central imperial forces were preparing to reclaim the breakaway provinces.

Epigraphy and Legends

The obverse legend reads C TETRICVS CAES, an abbreviation for Gaius Pesuvius Tetricus Caesar, occasionally recorded with interpunct separators such as C dot TETRICVS CAES. This title explicitly delineates the subordinate rank of the prince relative to the Augustus. On the reverse, the inscription PIETAS AVGG translates to the piety of the two emperors (Augustorum). Although Tetricus II held only the rank of Caesar, the use of the plural suffix AVGG was standard imperial practice to encompass the shared religious and administrative harmony of the father and son collegiate rule. Letterforms exhibit the late third-century western provincial style, showing compact lettering that is frequently compressed or truncated due to tight flan dimensions.

Typology and Chronology

Type RIC V Tetricus I 257 is assigned to the concluding phase of the Gallic Empire, dating between AD 273 and early AD 274, shortly before the surrender of Tetricus I and his son to the emperor Aurelian at the Battle of Chalons. Georg Elmer organized this series within the terminal emission of the dynasty, aligning the sacrificial implements type of Tetricus II alongside contemporaneous issues for Tetricus I depicting virtues such as Pax, Salus, and Fides. The cataloguing under Tetricus I within Roman Imperial Coinage reflects the convention of listing coins of a designated Caesar under the reigning Augustus who held sovereign striking authority. Variant distinctions within the broader PIETAS AVGG class rely primarily on subtle differences in bust drapery, the specific orientation of the pontifical vessels, and small mintmarks or symbols in the field or exergue, though type 257 generally lacks formal exergual markings.

Circulation and Hoard Evidence

Antoniniani of this type circulated intensively throughout Gaul, Britain, and adjacent western territories. Major British and French coin deposits, notably the Cunetio and Normanby hoards, contain thousands of radiates belonging to the joint reigns of the Tetrici, including specimens of RIC 257. Due to acute coin shortages and widespread acceptance of base billon, these pieces circulated alongside genuine central Roman coinage and spawned a massive wave of unofficial local copies known as barbarous radiates. Even after Aurelian reincorporated Gaul into the central empire in AD 274, the vast volume of Tetricic coinage prevented immediate demonetization. Type 257 continued to change hands for several years as small change until Aurelian's monetary reform gradually displaced the debased Gallic billon issues.
