The Ides of March coin, also known as the Denarius of Brutus or EID MAR, is a rare version of the denarius coin issued by Marcus Junius Brutus from 43 to 42 BC. The coin was struck to celebrate the March 15, 44 BC, assassination of Julius Caesar. It features a bust of Brutus, who was one of the assassins, on the obverse while the reverse features a pileus cap between two daggers. The coin was minted in both silver and gold. Approximately 100 of the silver coins are known to exist, but only three of the gold examples have survived. The coin is considered one of the rarest ancient Roman coins.
