Maximus Caesar: Silver Denarius Coinage of the Rome Mint

Historical Context

Gaius Julius Verus Maximus was the son of Emperor Maximinus I Thrax, whose reign lasted from 235 to 238 CE. Maximus held the subordinate rank of Caesar and was never Augustus. Denarii naming him belong to his father's imperial administration. The name Maximus here identifies the prince honored on the coins, not his father Maximinus, the contemporary emperor Pupienus Maximus, or a later emperor bearing the name Maximus.

The coinage presents an intended dynastic successor. His portrait accompanies titles and reverse images associating him with religious duty and military leadership, without demonstrating that he exercised independent supreme command. The addition of GERM, Germanicus, links him to the regime's victory titulature rather than proving a personal victory. The exact date of his appointment cannot be established from the broad catalogue ranges alone.

In 238, opposition to Maximinus led to civil conflict and the proclamation of rival emperors. Maximinus's march into Italy stalled at Aquileia, where his troops killed both father and son. This ended the dynasty represented by the denarii. Their modern survival does not by itself establish the extent of any ancient withdrawal, destruction, or suppression of the coinage.

Obverse Iconographic Composition

The catalogued denarius types discussed here show a bare-headed, draped bust of Maximus facing right. The youthful portrait and the title Caesar together express his position as heir under Maximinus I. The bare head should be interpreted within this particular series, rather than treated as a universal rule identifying the constitutional status of every Roman portrait.

Individual dies can differ in facial modelling, cloak folds, and the apparent viewing angle of the bust. Such differences require comparison with the relevant catalogue description and a legible coin. They do not by themselves establish a new mint, a precise date, or an additional official title. The presence or absence of a radiate crown alone is also insufficient to identify a coin's denomination.

Obverse Epigraphy and Inscriptions

The legends are Latin capitals arranged around the portrait. The checked catalogue entries document three obverse forms within the broader sequence before and after the addition of Germanicus.

1. IVL VERVS MAXIMVS CAES

• Expansion: Iul[ius] Verus Maximus Caes[ar]
• Translation: "Julius Verus Maximus, Caesar"
• Catalogue association: RIC IV.2 1, broadly 235-236 CE.

2. MAXIMVS CAES GERM

• Expansion: Maximus Caes[ar] Germ[anicus]
• Translation: "Maximus, Caesar, Germanicus"
• Catalogue association: RIC IV.2 2 and 3 denarius, broadly 236-238 CE.

3. MAXIMVS CAESAR GERM

• Expansion: Maximus Caesar Germ[anicus]
• Translation: "Maximus, Caesar, Germanicus"
• Catalogue association: RIC IV.2 4, broadly 236-238 CE.

CAES and the unabbreviated CAESAR both designate the prince's junior title. GERM is a victory epithet associated with the ruling family, not a declaration that Maximus became Augustus. The checked early denarius legend omits an initial C; that observation does not justify declaring every differently reported legend a forgery or transcription error without examining the evidence.

Reverse Iconographic Composition

The denarii develop themes of religious observance and the prince's relationship with military succession. The catalogued designs include three distinct compositions.

1. Priestly Emblems: The PIETAS AVG types show a jug between a curved staff or lituus and knife on the left, and a ladle or simpulum and sprinkler on the right. These implements evoke Roman religious duties. They do not by themselves prove that Maximus held a particular priesthood. Additional dishes or omitted implements should not be asserted without a clear type or die comparison.

2. Prince with Baton and Standards: On RIC IV.2 3 denarius, Maximus stands left in military dress, holding a baton in his right hand and a transverse spear in his left. Two standards stand behind him. The image presents the Caesar as the intended military successor; it does not document an actual command.

3. Prince with Globe and Reversed Spear: RIC IV.2 4 shows Maximus standing left, holding a globe in his extended right hand and a reversed spear in his left. Its associated legend is PRINCIPI IVVENT. This is a catalogued denarius composition distinct from the baton-and-standards design, not a transcription error created by a larger bronze denomination.

Reverse Epigraphy and Inscriptions

The checked silver denarius types carry the following Latin reverse legends around their designs.

1. PIETAS AVG

• Expansion: Pietas Aug[usti]
• Translation: "Piety of the Augustus"
• Association: Priestly emblems on RIC IV.2 1 and 2, paired respectively with IVL VERVS MAXIMVS CAES and MAXIMVS CAES GERM.
• The reference to Augustus does not confer that rank on Maximus; his obverse still names him as Caesar.

2. PRINC IVVENTVTIS

• Title represented: Princeps iuventutis
• Translation: "Prince of the youth"
• Association: The baton, spear, and standards design on RIC IV.2 3 denarius, with MAXIMVS CAES GERM.
• PRINC is abbreviated and does not alone determine the grammatical ending of the title.

3. PRINCIPI IVVENT

• Expansion: Principi iuvent[utis]
• Translation: "To the prince of the youth"
• Association: The globe and reversed-spear design on RIC IV.2 4, with MAXIMVS CAESAR GERM.
• PRINCIPI is explicitly dative and is documented on this silver denarius. It must not be rejected merely because other denarii abbreviate the title differently.

Typology and Documented Variants

The following checked OCRE entries are silver denarii attributed to Rome. They document more than the three entries often used to summarize the series; they are not a complete die census. All four describe a bare-headed, draped bust facing right.

The full identifiers matter, particularly where a catalogue number is shared by different denominations. RIC 2 is not assigned an exclusively early-236 production window here: the checked catalogue gives 236-238. The notion that it was struck only while new reverse dies were being prepared requires evidence beyond the legend pairing. Similarly, the reversed spear of RIC 4 should not be used to supply unverified spearhead details for every RIC 3 die. Classification rests on the documented combination of denomination, legends, bust, and reverse design.

Scholarly Debates and Attribution Limitations

Two interpretive limits are especially relevant to the denarii.

1. Appointment and Production Chronology: Maximus's status as Caesar is clear from the legends, but the date of appointment and the date at which each issue began are separate questions. An academic historical account places his appointment in 236, while OCRE dates the early denarius type broadly to 235-236. Those statements should not be converted into an exact date or a proved fifth-emission sequence without checking the relevant chronological study. The GERM legends distinguish a titulature group; they do not identify a production month.

2. Metrology and Alloy: A preserved coin's weight, a theoretical production standard, and its silver percentage are different measurements. Surface X-ray fluorescence can be affected by enrichment, so a methodological critique does not supply a corrected core composition for Maximus's denarii. The Butcher-Ponting volume cited as further reading concerns coinage from Nero to Trajan and cannot verify a third-century fineness range. No exact series mean, alloy percentage, or claim of unchanged silver content through 238 is asserted here. Such conclusions require a matched analytical dataset and an explanation of the sampling method.
