A rare gold aureus of Roman emperor Uranius Antoninus, commemorating a major milestone in Roman civic life, is one of the highlights of Gemini Numismatic Auctions’ Jan. 8 auction.

“All aurei of Uranius Antoninus are extremely rare” and the example in the auction is “apparently the fourth recorded specimen of one of the more interesting types,” according to the auction partners. Struck circa A.D. 253 to 254, the coin commemorates the games held by Philip I in honor of the millennium of Rome.

The coin, which is in Near Mint State, has an estimate of $75,000.

The auction, the Gemini group’s ninth, is being held in conjunction with the New York International Numismatic Convention. It offers Greek, Roman, Byzantine, Jewish and English coins. Consignments include the Harry N. Sneh Collection and the Phillip Davis Collection of Roman Republican Imitations.

Harlan J. Berk Ltd. and B&H Kreindler are parties in the joint venture.

All successful bids are subject to an 18 percent buyer’s fee, with a discount to 15 percent for certain payment methods.
