Mr. Halper also fetched a staggering $21.8 million, a record for sports memorabilia, during a weeklong auction at Sotheby's in 1999. Included in the Sotheby's sale was a game-used Mickey Mantle glove, purchased by actor-comedian Billy Crystal for $239,000.
''Barry was a dear friend, a valued partner for many years, and a decent, genuine person," said a statement released by Yankees owner George Steinbrenner. ''What a great baseball fan he was. I'll miss him dearly."
Mr. Halper amassed some 80,000 items, including uniforms of many Hall of Famers, an original ticket from the first World Series in 1903, and the jersey Lou Gehrig wore in his farewell speech at Yankee Stadium in 1939. Mr. Halper also owned oddities such as the false teeth worn by Ty Cobb, baseball's all-time leading hitter.
Also in Mr. Halper's collection were uniforms worn by Cobb, Walter Johnson, Cy Young, and Mantle, during his rookie season of 1951.
Mr. Halper had the contract finalizing the sale of Babe Ruth from the Red Sox to the Yankees, and a Honus Wagner baseball card.
''The Baseball Hall of Fame has lost a true friend in Barry Halper," said Dale Petroskey, president of the hall. ''Anyone who met Barry for the first time realized that his passion for the game was what set him apart."
