Cooper Flagg Jersey: $1M Sale & NBA Debut Hype

The hype around Cooper Flagg is no longer limited to parquet floors: it is also exploding in auction rooms.

Sotheby’s thus announced the sale, in a private transaction, of the jersey worn by the rookie of the Mavericks during the first half of his very first NBA game, for the tidy sum of a million dollars!

The jersey in question dates back to October 22, 2025, opening night against Victor Wembanyama’s Spurs. Cooper Flagg then achieved a double-double (10 points, 10 rebounds) despite a 4/13 shooting and the defeat.

Incidentally, this sale sets a new record for a first NBA jersey sold during the season, ahead of that of Victor Wembanyama, which fetched $762,000 in 2023. By the summer, a Cooper Flagg Summer League debut jersey had already reached $95,250, proof that collectors are active around the phenomenon.

With this million mark crossed, the industry in any case has new reasons to rely on collectors, while initiatives to generate souvenirs are multiplying in the NBA.
