“The denarius of Brutus commemorating the assassination of Caesar is one of the very few coins to be described in the ancient  literature. Cassius Dio relates that “Brutus stamped upon the coins which were being minted his own likeness and a cap and two daggers, indicating by this and by the inscription that he and Cassius had liberated the fatherland” (Roman  History, XLVII.25.3). Minted in 42 BC, while Brutus  and his fellow conspirators were on the march in northern Greece, the coin type was recalled by the victorious Mark Antony and Octavian  and melted down. Approximately seventy-five examples are known to exist, from 7 obverse and 25 reverse dies (8 obverse and 26 reverse dies also have been cited). In 2008, the finest example sold at auction for 350,000 Swiss francs (approximately $335,000); in 2011, another  coin struck slightly off center realized $546,250, a record for a silver Roman coin. The coin pictured above, which shows some porosity,  sold for $97,500. “
