The gold piece, slightly smaller than a US quarter, is more than two thousand years old. “It's priceless, but it still has a price tag,” said Arturo Russo, managing director of Numismatica Ars Classica. “To have a coin that commemorates such a well known event, such a famous event, an event that has changed completely the course of history is quite extraordinary.”
This gold coin, the “Eid Mar” (or “the Ides of March”), is said by the auction house to have been minted by Caesar’s betrayer Brutus, who is depicted on the front of the artifact. Rome’s freedom from Caesar’s tyranny is represented by the “cap of liberty” in-between the daggers. (The cap was traditionally given to emancipated slaves.)
There are three of these coins known to exist. One sold at Roma Numismatics in London in 2020 for a record-breaking 2.7 million (about $3.5 million.) The other is in the collection of the Deutsche Bundesbank.
The “Eid Mar” will be open for bidding when the auction takes place in person in Zurich, at the Hotel Baur au Lac, on 30 May.
