KNOXVILLE, Tenn. – A blizzard hammered much of Tennessee and the East Coast on Jan. 23, but at the Winter Case Antiques Auction, the records were falling faster than the snow. It turned out to be the most successful sale in company history, with a record sale total that exceeded the high estimate by 20 percent; a record-smashing 4,770 bidders from 70 companies participating in person, by phone, Internet, and written absentee bid; a 96 percent sell-through rate, and several individual artist auction records.
