In the past week, four Topps Rookie Debut Patch Autograph cards sold for more than $1 million — including an $8 million sale for Cooper Flagg’s card.
The cards, which came into existence only three years ago, have become instant grails in the collectibles market.
They’re being chased by baseball fans, collectors, corporations, investment funds and the players themselves.
Along with the Flagg sale, two other NBA cards commanded big numbers with Dylan Harper’s RDPA selling for $2.88 million and Kon Knueppel’s selling for $2.34 million.
Pete Crow-Armstrong’s MLB RDPA also sold for $1.098 million, just shy of the MLB-record set by Paul Skenes’ RDPA in 2025.
Several elements make these cards incredibly valuable, and rarity is only part of it. While every Rookie Debut Patch Autograph (RDPA) is a 1-of-1, plenty of 1-of-1 cards haven’t driven this level of demand.
Tied to the moment
The patch on the card is tied to a specific moment, but it’s the ultimate moment in a player’s career.

It’s the first time they step onto the diamond, court or pitch in their professional career.
The first game.
It can happen only once, and that special debut patch is adhered to the jersey ahead of time. The athletes score, run, jump and soak up the crowd noise as they live out a childhood dream.
Everyone knows exactly where that patch has been and can tie it to that first moment.
It also makes it easily understandable for regular fans. No one needs to explain what a Superfractor is or why one parallel commands so much more money than a dozen others.
Chain of custody
The important thing for Fanatics and Topps is proper chain of custody for the patches. It’s not enough that the patch is on the jersey. There has to be irrefutable evidence that it came from that specific jersey.
That’s why Fanatics works with the leagues and teams to ensure the chain of custody for the patches.
For the NBA debut patches, there are authentication stickers on the back of the patches that peek out through a window on the back of the card. That authentication number can be entered into the CGC certification database, where collectors can see the patch before it was placed into the card.
The authentication provides another layer of protection for the owners of the RDPA.
Marketing machine
If a card is made and no one knows about it, does it matter?
One of the biggest drivers of the value has been the Fanatics marketing machine behind them.
When Flagg signed his card, he did it in front of hundreds of fans while at Fanatics Fest. The social media clip was seen by hundreds of thousands — if not millions — of people.
The patch is shown on game broadcasts during a player’s debut. Collectors talk about it across social media. The hype around these cards is nonstop.
Then the subsequent stories add to the lore of the cards. It’s not just collectors vying for the cards, but players, their families, and companies such as Dick’s Sporting Goods putting their money into them.
Dick’s owns the Paul Skenes card, which sold for $1.11 million in March 2025 and holds the sales record for a baseball RDPA.
Cultural credibility
Owning one of the high-end RDPAs has been a badge of honor, ahen it won the Skenes card. And while the identity of the latest Flagg owner hasn’t been revealed, owning the card itself still holds weight
The RDPA has become a status symbol. Given the rarity, the moment they represent and the value, the RDPA are considered the holy grails of modern card collecting.
There are so few people who can say they own one of these cards, and even fewer who can say they own an RDPA of one of the best young players in the game.
Rookie Debut Patch Autographs have transcended other modern cards — and will continue to break records as players step into the spotlight.
