Quick Answer
Cooper Flagg’s rookie cards are in Topps’ first NBA season back, 2025-26. His base rookie is card #201 in 2025-26 Topps Basketball (he’s also the cover athlete), with more RCs in 2025-26 Topps Chrome, Topps Midnight and Topps Finest. Chrome rookies and rookie autographs are the top chases. His Duke-era Bowman U cards are pre-rookie cards, and his cards in the new 2026-27 Topps Flagship Basketball (Nov 5) are year-two cards.
Cooper Flagg didn’t just live up to the hype in year one. He beat it. The 2025 No. 1 pick won Rookie of the Year, became the youngest player in NBA history to score 50 points, and gave basketball collectors their first true superstar rookie of the Topps era.
If you’re trying to figure out which Cooper Flagg rookie card to buy, this guide breaks it all down: his official rookie cards, his popular pre-rookie cards, how to tell them apart, and where the new 2026-27 Topps Flagship Basketball fits. We stick to box contents and list prices, not market prices.
Cooper Flagg by the Numbers
Flagg was the National Player of the Year as a Duke freshman and the top recruit in his class. The Dallas Mavericks won the 2025 draft lottery and took him first overall.
His rookie season was historic. According to the NBA’s announcement, he averaged 21.0 points (first among rookies), 6.7 rebounds and 4.5 assists in 70 games. He scored 51 against Orlando on April 3, making him the youngest player ever to score 50, and he became only the second rookie, after Michael Jordan, to lead his team in points, rebounds, assists and steals. On April 27, 2026, he was named Kia NBA Rookie of the Year, the second-youngest winner after LeBron James.
Why His Rookie Cards Are Topps
2025-26 was the first season of Fanatics’ exclusive NBA trading card license, which ended Panini’s run as the NBA’s card maker since 2009. That made 2025-26 Topps Basketball the company’s first licensed flagship NBA set since 2009-10, and Topps put Flagg on the cover. Every officially licensed Flagg rookie card, with the Mavericks name and uniform, comes from Topps.

2025-26 Topps Basketball
This is the start of everything. His base rookie, card #201, is the most affordable Flagg RC and the card most collectors want first. The set also has his Real One rookie autograph and a Triple Rookie Photoshoot autograph with Dylan Harper and Kon Knueppel. Topps even made a one-of-one “First Card” version of his rookie.
2025-26 Topps Chrome Basketball
Chrome is the modern rookie card standard. Released December 18, 2025, it has Flagg’s Chrome rookie with a full rainbow of refractors, from numbered colors down to the Superfractor 1/1, and his Chrome rookie autographs are the set’s top chase. If you want one “key” Flagg rookie, his Topps Chrome RC is it for many collectors.
2025-26 Topps Midnight and Finest
These are high-end hobby products. Midnight hobby boxes list at $619.99 for one pack with three autographs, and Finest brings back Topps’ famous chrome brand with a $499.99 hobby box. Both have Flagg in their rookie class, and both are built for collectors chasing autographs and low-numbered parallels.
Cooper Flagg Pre-Rookie Cards
Flagg had a huge card market before he ever played an NBA game, thanks to Topps’ college and prospect licenses. The best known are:
- 2024-25 Bowman Chrome University #16, from his Duke season. His Chrome U autographs are some of his most famous cards.
- 2024 Topps Chrome McDonald’s All-American cards from his high school all-star game.
- 2024 Bowman University NOW cards, made in limited windows.
- 2025 Topps NOW Basketball #D1, a draft-night card that was sold for a limited time.
Rookie or not?
Collectors treat his college and high school cards as pre-rookie cards, and opinions vary on draft-night print-on-demand cards. If you want an official rookie card, look for the RC logo on his 2025-26 NBA-licensed Topps cards.
Where 2026-27 Topps Flagship Basketball Fits
2026-27 Topps Flagship Basketball releases November 5, 2026. Flagg is on the checklist as a second-year star, so these are year-two cards, not rookie cards. They’re a fun, affordable way for fans to add new Flagg cards, parallels and inserts, and the set’s rookie headliners, AJ Dybantsa, Darryn Peterson and Cameron Boozer, are a big reason to rip it too.
Hobby boxes list at $169.99 on Topps.com with one autograph or relic, Mega boxes at $59.99 and Value boxes at $29.99. Our 2026-27 NBA rookie card guide breaks down the new rookie class.
How to Tell a Real Cooper Flagg Rookie Card
Flagg has a lot of cards on the market, so it pays to check before you buy a single:
- Find the RC logo. His official rookie cards carry the RC logo and come from 2025-26 NBA-licensed Topps products.
- Check the team and uniform. Rookie cards show him as a Dallas Maverick. Duke and high school cards are pre-rookie cards.
- Read the back. The year, set name and card number are printed on the back. His 2025-26 Topps Basketball base rookie is #201.
- Match the parallel exactly. A numbered refractor and a base Chrome rookie are very different cards, so compare the color and serial number to the listing.
- Buy graded cards from trusted sellers. For expensive cards, a slab from a major grading company adds a layer of authentication.
And if you pull a Flagg yourself, sleeve it and put it in a top loader right away. A clean, sharp card is the one that grades well.
Which Cooper Flagg Card Should You Buy?
- On a budget: his 2025-26 Topps Basketball base rookie #201, or year-two cards from 2026-27 Topps Flagship retail boxes.
- The key rookie: his 2025-26 Topps Chrome RC, and a numbered refractor if you want something rarer.
- High end: rookie autographs from Topps Chrome, Midnight and Finest, or a low-numbered parallel.
- For prospect fans: his 2024-25 Bowman Chrome University cards from Duke.
Before you buy any single card, check recent sold prices and condition. Our guide on how much your sports cards are worth shows you how, and our grading guide explains when a slab is worth it.
