American auction house Zachys took a 2003 record US$4.5m last weekend.
Large numbers of bidders attended the sale despite a two-day snowstorm burying Manhattan.
Zachys president Jeff Zacharia said the sale broke several world records. A case of 1982 Léoville-Las-Cases went for US$5,265 and a case of 1990 Cheval Blanc fetched US$9,360.
The highlight of the sale was a 33-bottle superlot of 1982 Bordeaux imperials (one imperial is equal to eight standard bottles). The collection, which included first growths and the likes of Ausone, Pétrus and La Mission Haut-Brion, eventually fetched $245,700, more than three times its low estimate.
The other big moneymakers included a case of 1982 Le Pin, which went for US$49,140, and a case of 1995 Montrachet from Domaine de la Romanée-Conti, which fetched US$30,420.
In all, Zachys, a retailer in suburban Scarsdale, NY, sold 95% of the 1,911 lots offered.
