A $515 purchase has turned into one of the biggest windfalls in modern sports-card history.
Collector Jason Williams of South Carolina spent $515 for a Dallas Mavericks spot in a livestreamed box break in August. What emerged was the card everyone was chasing: Cooper Flagg’s one-of-one Topps Chrome Rookie Debut Patch Autograph, featuring Flagg’s signature and the NBA debut patch taken from the jersey he wore in his first professional game.
On Friday, that card sold through Fanatics Collect for $8.04 million after a dramatic late bidding war. According to Fanatics, the price climbed from approximately $3.5 million late Thursday night to the final figure in the early hours of Friday morning.

The sale makes it the third-most expensive NBA card ever sold and, the most expensive single-player NBA card on record. Only two dual-player cards featuring combinations of Michael Jordan, Kobe Bryant and LeBron James have sold for more.
What makes the story even more remarkable is what Williams turned down along the way.
Before the card was pulled, the Mavericks had publicly offered an enormous bounty to whoever found it: two premium lower-level season tickets for 32 years, matching Flagg’s No. 32 jersey, along with a signed game-worn Flagg jersey, player experiences and other perks. Williams ultimately chose not to exchange the card for the package and instead took it to auction.
Financially, the decision could hardly have worked out better.
The $8.04 million result shattered the previous record for a Flagg card, which had stood at $366,000. It also established a new benchmark for the rapidly growing Rookie Debut Patch Autograph market, which combines a one-of-one rookie card with an authenticated patch from the player’s first NBA game.
Flagg’s card was graded PSA Gem Mint 10, with his autograph also receiving a 10 grade, further adding to its appeal among high-end collectors.
For Williams, though, the story can be reduced to one almost unbelievable equation.
He paid $515 for a chance in a box break, landed one of the rarest basketball cards ever produced, passed on decades of Mavericks tickets and memorabilia, and eventually walked away with an $8.04 million sale.
Sometimes turning down the viral offer really does pay off.
