A spectacular Roman gold medallion sold to an anonymous phone bidder for $2.327 million at Classical Numismatic Group LLC's Triton XXVI auction in New York City Wednesday, shattering the record for the highest price paid for a Roman Imperial coin and electrifying a ballroom packed with onlookers.

The huge coin, a unique 10-aurei gold medallion of the Roman Emperor Diocletian (reigned AD 284-305), is larger than a U.S. $20 gold piece and nearly twice as heavy, with a powerful portrait of the emperor on the obverse and the seated figure of a muscular god Jupiter on the reverse. The largest Roman gold coin to sell at auction in well over a century, it was lot 830 and the highest-value coin in the two-day Triton XXVI auction, which realized just under $14 million total including buyer's premium, nearly double the presale estimate. The sale took place at the posh Intercontinental Barclay Hotel in Manhattan as part of the week leading up to the 51st 2023 New York International Numismatic Convention, where coin dealers and collectors gather from all over the world.

CNG auctioneer Jeff Rill expertly managed the drama-filled bidding for the piece, which started with an internet entry of $475,000 on the firm's website, www.cngcoins.com, then moved to a dwindling handful of floor bidders and two agents on cell phones representing remote bidders as the price rocketed past the $500,000 estimate and beyond the $1 million mark. Gasps escaped the audience as the price moved beyond the $1.65 million record for a Roman imperial coin, which had stood since 2008.

A tense pause stretched out for what seemed like an eternal 90 seconds after the bidding reached $1.9 million and Rill said with a phone agent holding up his paddle and the last floor bidder slowly shaking his head. The room erupted into applause and cheers when Rill finally called out, The 22.5% buyer's premium brought the medallion's final price realized to $2,327,500.

Rill said.

The medallion, termed a denio by specialists, is nearly 40mm in diameter and weighs 53.65 grams. It is believed to have been struck in AD 294 to mark Diocletian's tenth anniversary of rule. The Diocletian denio was encapsulated by Numismatic Guaranty Corporation with an extraordinary grade of Choice AU?, Strike: 5/5, Surface 5/5, Fine Style. "NGC Ancients is pleased to have handled this exciting piece, which stands out as one of the finest Roman medallions in existence," said David Vagi, head of NGC's ancients division.
