Caitlin Clark's card sales hit $366K then $660K in 2025.

In March 2025, a Caitlin Clark rookie card sold for $366,000.

A different signed Clark card brought a record $660,000 that July.

The first sale was a one-of-one rookie card bearing her signature.

It fetched $366,000 at Goldin on March 30, 2025.

The card was the 2024 Panini Prizm WNBA Signatures Gold Vinyl.

It featured Clark's blue-ink autograph and carried a perfect PSA 10 grade.

The sale established a new record for any women's sports card.

It surpassed the previous high of $266,400.

That record had been set by a 2003 Serena Williams NetPro rookie card in May 2022.

Then on July 24, 2025, another one-of-one Clark rookie card appeared at the Fanatics Collect July Premier Auction.

This time it was a 2024 Panini Flawless Platinum Rookie "Logowoman" Patch card.

Bidding climbed to $336,000 before the auction entered extended time.

Eventually, 26 bidders pushed the final price all the way to $660,000.

The card also carried a personal touch.

Clark wrote "769 points and counting" beside her autograph.

The figure was not random.

It represented her remarkable rookie scoring total.

To understand how dramatically the market had changed, consider this.

The most expensive WNBA card in February 2023 was a Sabrina Ionescu rookie that sold for only $10,800.

Clark's rookie campaign in 2024 provided plenty of reasons for collectors to take notice.

She was selected No. 1 overall by the Indiana Fever.

She started all 40 games.

She averaged 19.2 points, 5.7 rebounds, and a league-leading 8.4 assists.

She finished the season with 337 assists, setting a new WNBA single-season record.

Her 769 points and 122 three-pointers also established new rookie records.

Clark received 66 of 67 possible Rookie of the Year votes.

She helped Indiana reach the playoffs for the first time since 2016.

The attention surrounding her performances quickly extended beyond the court.

Indiana averaged a league-record 17,035 fans per home game.

That was a massive increase from approximately 4,000 the previous season.

Clark's four-year rookie contract totaled $338,056.

Her $660,000 card sale was worth nearly twice her entire agreement with Indiana.

Even more striking, 14 of her cards had individually outsold her full $78,066 salary for the 2025 season.

That financial gap has begun to change under the WNBA's new collective bargaining agreement.

Clark's 2026 salary increased from $85,873 to $528,846.

Her commercial value, meanwhile, continues to climb.

Dick's Sporting Goods signed Clark as its first-ever brand partner in a multi-year deal that also includes Foot Locker.

Clark called the partnership a "full-circle moment" in the announcement.

"Dick's Sporting Goods was always a stop before the start of any sports season when I was growing up," she said.

"Being the first ever brand partner for both them and Foot Locker is a really special full-circle moment."

Through the partnership, Clark's brand of signature footwear, apparel and product lines at Nike will reach fans across the world.

The collectibles market has offered perhaps the clearest indication of her growing value.

Her rookie cards have become a benchmark for women's sports memorabilia.

The $660,000 sale stands as the highest price ever paid for a women's sports card.

It also ranks among the most valuable basketball cards of any kind sold in 2025.

Industry observers are watching to see whether the momentum holds.

Clark's on-court performance in 2025 and beyond will likely influence future auction prices.

So will the continued growth of the WNBA's visibility and fan base.

The league's new collective bargaining agreement has raised player salaries significantly.

But for collectors, the story is about scarcity and demand.

One-of-one cards are the rarest items in the trading card world.
