With its latest auction, Grey Flannel Auctions broke its own record for highest auction price ever paid for a basketball jersey.

An iconic jersey worn by Julius “Dr. J” Erving during the first-ever halftime Slam Dunk Contest in 1976 soared to a closing price of $188,321, helping the 1,000-lot auction total $1.73 million. All prices quoted include the 20-percent buyer’s premium.

Heritage Auction Galleries held its latest Sports Collectibles Signature Auction May 2-3 in Dallas. The auction realized $3,683,484 for 877 lots.

“Any potential consignors concerned that the stormy U.S. economic climate might throw a shadow over the collectibles market should have had those fears eliminated by this event,” said Chris Ivy, director of Sports Auctions for Heritage. “In both trading cards and memorabilia, we saw estimates obliterated in some of the fiercest bidding wars we’ve ever witnessed.”

As expected, the top price of the auction was paid for ownership of the T206 Honus Wagner.

A 1952 Topps Mickey Mantle card sold for $96,000 ($112,800 wth the buyer’s premium) Sunday in Memory Lane’s Spring Fever Rarities Auction, setting what could be a new record price for a PSA 8 graded ’52 Mantle specimen. A PSA 9 '52 Mantle for fetched a whopping $282,587 in 2007.

Other highlights of the auction included a 1951 Bowman Willie Mays card graded PSA 9, which brought $85,775, and a PSA 8 Babe Ruth signed baseball, which sold for $81,075.

In the hearts and imaginations of fans who were bidding, Jackie Robinson hit a home run, as his 1951 game-used home jersey scored $341,779 in Grey Flannel’s holiday auction.

Carrying impeccable provenance, the Brooklyn Dodgers flannel jersey featured Robinson’s number “42” on the back, the team name on the front and the chain-stitched name J. Robinson inside its collar.
