The Brutus Eid Mar Denarius is not just any ancient coin; it’s a symbol of Rome’s turbulent history, marked by power struggles and the quest for republicanism.

Minted by Marcus Junius Brutus in 42 BC, this silver coin is more than currency—it’s a political statement. Brutus, known for his role in the assassination of Julius Caesar, used these denarii to communicate his version of liberty—EID MAR, short for Eidibus Martiis (the Ides of March), underscores the date of Caesar’s assassination.


To appreciate the Brutus Eid Mar Denarius fully, one must understand the historical backdrop against which it was minted.

Following the death of Caesar, Rome was plunged into chaos, with various factions vying for control. Brutus and his co-conspirators believed that Caesar’s death was a necessary act to restore the Roman Republic. However, the resulting civil wars painted a different picture—one of ambition and continuous strife.

The Eid Mar Denarius was minted as Brutus prepared for battle against Mark Antony and Octavian, who were staunch supporters of Caesar. This coin was not only a means of funding the war but also a tool to spread the message of the liberators’ cause.

Design features

The design of the Brutus Eid Mar Denarius is both intricate and symbolic.

  • The obverse of the coin features a portrait of Brutus, showcasing him in a heroic light. This was a bold move, as it was uncommon at the time for living persons to appear on coins, suggesting Brutus’s confidence in his cause and status.
  • The reverse is even more telling, with two daggers flanking a pileus (a cap that symbolized freedom for slaves). This imagery is a clear nod to the assassination, representing the ‘liberation’ of Rome from tyranny. The inclusion of the date, Eid Mar, serves as a reminder of the deed, solidifying the coin’s purpose as a political manifesto.
