A one-of-one Victor Wembanyama rookie card has changed hands for $5.11 million in a private sale, a number large enough to make even the most hardened collectibles trader blink politely and keep refreshing the market charts.

The deal was brokered by Fanatics Collect. The card is Wembanyama’s 2023-24 Panini Prizm Black parallel rookie card, graded Gem-Mint PSA 10. In collector language, that means it is both extremely rare and in top certified condition, which is basically the whole plot.

According to The Athletic, the sale makes it the most expensive known non-autographed NBA card ever sold. It also ranks as the fourth-highest known NBA card sale publicly recorded, placing the San Antonio Spurs star’s rookie card in the same high-end conversation as cards featuring Michael Jordan, Kobe Bryant, LeBron James, and other all-time names.
