A unique 1-of-1 signed basketball card featuring Michael Jordan and Kobe Bryant sold for a record $12.932 million at auction on August 23, 2025, surpassing all previous sports card sales. The card, authenticated by PSA, was sold through Heritage Auctions and set a new benchmark as the most expensive sports collectible card ever sold. Originally purchased for $25,000 in 2013 and flipped for $170,000 in 2015, the card was held for a decade before fetching the record price. The buyers included Canadian businessman Kevin O'Leary, who revealed he was part of a trio that acquired the card. O'Leary described the auction as highly competitive, with the final hammer price reported at $12.9 million. The sale eclipsed previous records, including those set by iconic baseball cards such as Mickey Mantle's. The transaction highlights the growing value and resilience of high-end collectible cards in the market.
