Crispus Coins: The Tragic Story of Constantine's Executed Son
Who was Crispus, and why do his coins matter? Crispus was the eldest son of Constantine the Great and served as Caesar from AD 317 until his sudden execution in 326. His surviving bronze coins preserve the portrait and titles of a prince whose career ended in one of the most debated episodes of the Constantinian dynasty.
For collectors, Crispus offers a direct connection to Constantine's rise to sole rule, the civil war with Licinius, and the complicated dynastic politics of the early fourth century.
Who Was Crispus?
Crispus was born probably around AD 303–305 to Constantine and Minervina. Ancient sources disagree about Minervina's exact status, so it is safer not to describe her too confidently as either a formal wife or a concubine.
On 1 March 317, Constantine elevated Crispus to the rank of Caesar alongside Constantine II and Licinius II. Still very young, Crispus was given an increasingly important role in the western empire and was active in Gaul, where he gained military prestige along the Rhine frontier. citeturn111357search0turn111357search2
What Did Crispus Accomplish in the War Against Licinius?
Crispus's best-attested military achievement came in AD 324 during Constantine's final war against Licinius. Constantine placed him in command of the fleet. Crispus defeated Licinius's admiral Amandus in the waters around the Hellespont, helping Constantine carry the war into Asia Minor before the final victory at Chrysopolis. citeturn111357search0turn111357search5
This is an important distinction from later retellings that credit Crispus with victories against Goths. The surviving evidence more securely associates his western career with Gaul and his most famous command with the naval campaign against Licinius.
Why Was Crispus Executed?
In AD 326, Constantine ordered Crispus executed, traditionally at Pola, modern Pula in Croatia. The exact reason remains uncertain.
Later ancient writers connected the episode with accusations involving Fausta, Constantine's wife and Crispus's stepmother. Fausta herself died soon afterward under mysterious circumstances. Because the surviving accounts were written after the events and disagree on important details, historians cannot reconstruct the sequence with certainty.
Was Crispus Subjected to Damnatio Memoriae?
After his execution, Crispus's name and memory were suppressed in some official contexts, a process commonly described as damnatio memoriae. His name was erased from some inscriptions and his public standing disappeared.
That does not mean Rome achieved a “total erasure.” Crispus remained visible in surviving texts, inscriptions, portraits, and especially coins. His coinage is one reason his place in Constantinian history is still so tangible.
What Do Crispus Coins Look Like?
Crispus was represented on several bronze issues during his years as Caesar. Modern references commonly classify many of these pieces in the AE2/AE3 size range, depending on the exact issue. His portraits and legends vary by mint and date.
Common obverse legends include forms such as CRISPVS NOB CAES and FL IVL CRISPVS NOB CAES. Reverse types are much more varied than a single “military” theme and can include Sol, vota inscriptions within wreaths, camp gates, military standards, Victory, and other imperial designs. Examples were struck at mints including Trier, Siscia, Aquileia, London, and others. Published RIC examples confirm multiple AE2/AE3 types and a wide range of reverses.
Are Crispus Coins Rare?
Not every Crispus coin is rare. Many bronze issues survive in enough numbers that collectors can obtain an example without pursuing an elite rarity.
The appeal is historical rather than dependent on exaggerated scarcity. Crispus's relatively short tenure as Caesar, his important role in Constantine's victory over Licinius, and his abrupt execution give his coins a strong narrative connection to one of the most dramatic imperial families in Roman history.
Why Collect a Coin of Crispus?
A Crispus bronze can be a particularly good choice for collectors interested in Constantine the Great, Late Roman history, dynastic politics, or the transition of the empire in the early fourth century.
When choosing one, look for a clear attribution, an identifiable portrait, readable portions of the legend, honest surfaces, and a seller who stands behind authenticity. Because Crispus's coinage includes many mints and reverse types, the exact attribution matters more than a generic label such as “coin erased by Rome.”

A Coin That Preserved What Politics Tried to Suppress
Crispus does not need an exaggerated story to be fascinating. He was Constantine's son, a Caesar from 317, a successful naval commander in the decisive war of 324, and an imperial prince executed only two years later for reasons that remain uncertain.
His coins survived the political suppression of his memory and still let collectors hold a contemporary object from that extraordinary career.
