Roman Republic
85–42 BC
Kinzer Coins
Brutus struck the most famous coin in Roman history the year he killed Caesar. His coinage spans the final decades of the Republic — from his 54 BC moneyer issues invoking his anti-monarchical ancestors to the Eid Mar denarius openly celebrating the assassination — and every piece tells part of the same story.
Born around 85 BC into one of Rome's most historically resonant families, Marcus Junius Brutus traced his lineage to Lucius Junius Brutus, the legendary founder of the Republic who overthrew Rome's last king. That ancestry was not incidental — it was the ideological foundation on which he built his entire political identity, visible in his coinage years before the Ides of March. Philosopher, statesman, and Stoic, Brutus was pardoned by Caesar after Pharsalus, promoted politically, and then led the conspiracy that killed him in 44 BC. The Republic he died trying to save was already gone. His coins are among the most historically charged artifacts from any ancient civilization — direct metal witnesses to the moment Rome stopped being a republic.
The Eid Mar Denarius
No ancient coin is more famous. The Eid Mar denarius openly celebrated the assassination of Julius Caesar — something almost unimaginable in Roman coinage, where even criticism of the powerful was encoded in careful imagery. Here the message is explicit: two daggers flanking a liberty cap on the reverse, the inscription EID MAR for the Ides of March, and Brutus' own portrait on the obverse. It is the only Roman coin that publicly names a specific act of political violence and declares it a liberation. Struck from a military mint in the east as Brutus raised forces against Antony and Octavian, authentic examples are extraordinarily rare and rank among the most valuable ancient coins ever sold. The gold aureus version is rarer still. For collectors and historians alike, the Eid Mar represents something no other ancient coin does: a political manifesto struck in silver at the exact moment of the act it commemorated.
Obverse
Type: Portrait of Brutus right — one of the very few Republican coins to feature a living Roman's portrait. The decision to place his own face on the coin was itself a statement of the extraordinary circumstances.
Legend: BRVT IMP L PLAET CEST — naming Brutus as imperator and his moneyers Lucius Plaetorius Cestianus.
Reverse
Legend: EID MAR — "Ides of March." The inscription that names the moment directly and transforms the coin into a political monument.
Type: A liberty cap (pileus) between two daggers — the assassination weapons flanking the symbol of freedom. The most charged reverse composition in all of Roman numismatics.
The Eid Mar is the only coin in Roman history that openly names a political assassination and declares it liberation. Two daggers, a liberty cap, and three words. No other ancient coin compresses more history into less space.
The Complete Coinage of Brutus
Brutus' numismatic legacy spans three distinct phases: his 54 BC moneyer issues when he was building a Republican political identity; the period immediately surrounding Caesar's assassination; and his eastern military issues struck during the civil war against Antony and Octavian. Each phase tells a different part of the story, and together they constitute one of the most coherent political narratives in all of ancient coinage.
54 BC Moneyer Denarii
Struck before the assassination, these issues reveal the ideological foundations of Brutus' later actions. Famous types depict his ancestor Lucius Junius Brutus — founder of the Republic — alongside Gaius Servilius Ahala, celebrated for killing a would-be tyrant. In hindsight, almost prophetic. Essential for understanding Brutus the thinker before Brutus the assassin.
Eid Mar Silver Denarius
The most famous Roman coin. Extraordinarily rare and among the most valuable ancient coins ever sold at auction. The portrait of Brutus, two daggers, the liberty cap, and EID MAR on the reverse. A direct numismatic record of one of history's most consequential political acts. Even reproductions are instantly recognizable worldwide.
Eid Mar Gold Aureus
Rarer than the silver denarius and among the greatest treasures of Roman numismatics. The gold aureus version of the Eid Mar type has achieved some of the highest prices ever recorded for an ancient coin at auction. The pinnacle of Republican coin collecting — a true once-in-a-generation acquisition.
Eastern Military Issues
Struck from mobile military mints in Greece, Macedonia, and Asia Minor as Brutus raised forces against Antony and Octavian. These civil war issues blend Roman political propaganda with eastern artistic influence and often name Brutus as imperator. Significantly rarer than mainstream Republican denarii and highly sought by advanced collectors.
Portrait Denarii
Brutus' portrait appears on several types beyond the Eid Mar — remarkable in itself, as placing a living Roman's face on coinage was deeply controversial and associated with Caesar's own unprecedented self-promotion. These portrait types reflect Brutus embracing the very tactics he had condemned in Caesar, justified by the stakes of the civil war.
KOSON Gold Staters
The intriguing Dacian and Thracian gold staters sometimes associated with Brutus' eastern campaigns. Whether directly linked to Brutus or connected more broadly to the Republican forces operating in the region, these high-purity gold coins feature Roman Republican-influenced imagery and remain one of the most fascinating collecting areas adjacent to the Brutus numismatic story.
How to Collect Brutus
The full Brutus coinage spans an enormous price range — from attainable 54 BC moneyer denarii to the Eid Mar, which ranks among the most expensive ancient coins ever sold. Most collectors approach Brutus through the accessible earlier Republican issues and work toward the rarer civil war types, with the Eid Mar representing the ultimate acquisition for any Republican collection.
Start Here
The 54 BC moneyer denarii — the Lucius Junius Brutus ancestor types are genuinely attainable and tell the essential ideological backstory to the Ides of March. These are among the most historically rich Republican denarii available at accessible prices, and a natural starting point for any Brutus or late Republican collection.
Go Deeper
Eastern military denarii and portrait issues for specialist collectors. The Eid Mar silver denarius for those with serious Republican collecting ambitions — rare, significant, and unmistakable. Pair with a Julius Caesar portrait denarius to tell the complete Caesar-and-Brutus story in two coins.
Brutus is essential for any serious Roman Republican collection — and his coinage is unique in that it tells a complete political narrative from beginning to end, across thirty years of minting. The 54 BC ancestor types show the ideological groundwork. The Eid Mar is the act itself. The eastern military issues are the aftermath. Very few figures in ancient numismatics left behind a coinage that coheres so completely into a single historical argument. Whatever level you approach him — moneyer denarii, civil war issues, or the Eid Mar itself — you are collecting the coins of the man who asked the most consequential political question in Roman history: can one man's life justify the death of a republic?
