A rare Roman Imperial coin from a short-lived reign during a civil war highlights Freeman & Sear’s Manhattan sale No. 3, scheduled for Jan. 3 in New York City.

The silver denarius of L. Clodius Macer, struck at Carthage circa April to October A.D. 68, is “extremely rare, apparently from an unpublished die pairing and one of only a handful of Clodius Macer portrait denarii known to exist.” The abbreviation S C (Senatus Consulto) “in this case mistakenly inverted,” plus his depiction without a laurel crown, suggests he was revolting against Nero and not the Senate, according to the catalog.

In Nearly Extremely Fine condition and “toned,” the coin has an estimate of $60,000.

It is the highlight from the firm’s auction, which is scheduled in conjunction with the New York International Numismatic Convention. The auction offers 236 lots of Greek, Roman and Byzantine coins, and 52 lots of Celtic coins “from Cabinet Q.”

An 18 percent buyer’s fee applies to all successful bids, with a discount to 15 percent for certain payment and bidding methods.
