Former Duke basketball star Cooper Flagg made his first appearance in NBA action during the 2025 Las Vegas Summer League, just days after being taken No. 1 overall by the Dallas Mavericks in the 2025 NBA Draft. Though he only suited up for two games, his jerseys from those outings have been fetching staggering prices. On Tuesday, Flagg’s jersey from his Summer League debut sold for a record-breaking $95,250 — the highest price ever paid for a Summer League jersey.
Cooper Flagg’s meteoric rise in the basketball world continues to make headlines — and set records. His Las Vegas Summer League debut jersey didn’t just become the priciest debut jersey from a rookie; it is now the most expensive Summer League jersey ever sold, fetching an astonishing \$95,250 at Sotheby’s. The sale comes just a month after his NBA Combine jersey went for \$22,860, reinforcing that “Capture the Flagg” has more than one meaning among NBA fans and collectors.
While the Maine native’s official rookie season with the Dallas Mavericks is still months away, the rush to secure his early-career memorabilia shows no sign of slowing down. The former Duke star and National Player of the Year enters the league as one of the most hyped prospects of the past two decades — but unlike most No. 1 overall picks, he’s joining a contender, not a rebuilding team.
The Mavericks are eyeing an NBA title in 2025–26 despite star guard Kyrie Irving’s extended absence following a torn ACL in March. With a deep, experienced roster, Dallas still sees Flagg as a future franchise cornerstone, but head coach Jason Kidd plans to deploy him primarily at point guard due to the team’s crowded frontcourt.
Until the season tips off, Flagg won’t be adding new NBA highlights to his résumé — but that hasn’t stopped fans from making his memorabilia a hot commodity.
