Heritage Auctions two-day Winter Platinum Night Sports Auction was a newsmaker many times over, and not just because nearly 2,600 bidders from around the world participated in an auction that realized $25,518,284. Nearly 75 records were set during the Feb. 26 and 27 sale, from sporting-event tickets to jerseys to cards to Ted Williams Triple Crown-season bat to Michael Jordans game-worn Air Jordans. Even a presidential basketball slam-dunked early estimates, when a ball autographed by President Obama, Kobe Bryant, LeBron James, Magic Johnson and Carmelo Anthony sold for $99,000, more than eight times its pre-auction estimate. And Amelia Earharts flight cap, worn when she made her famous first flight across the Atlantic Ocean in 1928, sold for $825,000. Thats more than 10 times its pre-sale estimate. One of seven known ticket stubs from Jackie Robinsons big-league debut in the spring of 1947 sold for $480,000, making it the most expensive sporting-event ticket ever sold at auction. Mark Attanasio, owner of the Milwaukee Brewers, was the buyer of the Robinson ticket stub. The only known full ticket from Michael Jordans NBA debut sold for $468,000. There were 72 tickets in this auction, and together they realized $2.1 million. Two more sports legends saw tickets to their milestone moments reach new highs. A ticket stub to Lou Gehrig Appreciation Day at Yankee Stadium on July 4, 1939, sold for $108,000 to become both the most expensive Gehrig ticket and most valuable pre-war ticket ever sold. Only six known examples survive from the day more than 60,000 people heard, in person, the Yankees first baseman deliver one of the most memorable speeches in sports history: For the past two weeks you have been reading about a bad break. Yet today I consider myself the luckiest man on the face of the earth. And a full ticket to the 1996 Greater Milwaukee Open, where Tiger Woods made his debut, sold for $99,000. Thats the highest-graded example, at PSA Mint 9, and now the worlds most valuable Woods ticket. It originally cost $25. The jersey worn by Mickey Mantle when he played his final game as a New York Yankee on Sept. 28, 1968, sold for $2,190,000. Thats the highest price ever paid at auction for a Mantle jersey, shattering the previous record of $1,320,000 set at Heritage Auctions in August 2018. And the Dallas Mavericks Dirk Nowitzki scored his biggest jersey sale ever when a photo-matched jersey worn during his MVP season in 2006-07 sold for $23,400. A pair of Air Jordan 1s worn by Michael Jordan during the Chicago Bulls 116-107 loss to the Milwaukee Bucks on April 1, 1986, sold for $675,000, breaking the previous record of $615,000 set almost two years ago. The Air Jordans, photo-matched to that game, were slightly altered from their standard format to mitigate the threat to Jordans healing bones after he broke his foot in October 1985. The Air Jordans soles were replaced with those used on the Nike Dunk, which were both softer and wider. Among baseball collectors, few pieces of lumber are more vaunted or valuable than those swung by Ted Williams, the last player to hit over .400 in a season. So it should not surprise that a game-used and signed Hillerich & Bradsby bat from Teddy Ballgames 1947 Triple Crown season now holds the record for the most expensive Williams bat ever sold at auction: $336,000. There were numerous Jackie Robinson records set during this auction, which featured a historic collection of memorabilia related to the man who, 75 years ago this spring, broke baseballs color barrier. Among the auctions top lots was his March 1946 American Baseball Bureau questionnaire, which realized $1,680,000. Seth Kaller Inc. was the winning bidder for Robinsons questionnaire and has arranged for its display at the Jackie Robinson Museum, which is set to open this summer in New York City. Robinsons 1948 Leaf card, graded PSA NM-MT 8, is also now his most valuable rookie card, having sold for $468,000. Of the more than 1,500 submissions to PSA, only seven have ever been graded higher than this example. Some of the other new records set were for a 1912 E300 Plows Candy Honus Wagner card, graded PSA NM 7, bringing $312,000. Thats the highest price ever realized for a card from the so-called Miracle Set from which there are only 175 known survivors. From that same set, a Ty Cobb card graded PSA NM 7 sold for $222,000, a record for that rarity. For more results from Heritage Auctions Winter Platinum Night Sports Auction, visit www.HA.com.
