The Top 5 Sports Cards Heating Up
5. Darian Mensah
Darian Mensah, the quarterback for the Miami Hurricanes, opens this week's list after an impressive start to his college football career. Through his first three games at Miami, Mensah has completed 71 of 79 passes for 873 yards, 11 touchdowns, and zero interceptions. Miami has also won all three games during that stretch.
His latest performance was particularly impressive. Mensah completed 24 consecutive passes against Wake Forest, and when combined with his previous game, he reached 35 straight completions. That streak set a new all-time ACC record.
His on-field production is already driving up demand for his sports cards, particularly his Bowman Chrome University prospect autograph cards.
Key Card Movements:
-
2025 Bowman Chrome University Prospect Auto 1st (Raw): $65 → $82
-
2025 Bowman Chrome University Prospect Auto Blue Refractor /150 1st (Raw): $190 → $280

Mensah's combination of efficiency, touchdown production, and Miami's undefeated start has created noticeable momentum around his football cards.
4. Drew Lock
Drew Lock of the Seattle Seahawks takes the fourth spot after unexpectedly stepping into the starting quarterback role following Sam Darnold's injury. Lock took over during Seattle's season opener and then started the team's Week 2 matchup. Across those two opportunities, he threw for 422 yards, four touchdowns, and zero interceptions.
Seattle won both games, including a dominant 31-7 victory over Arizona. Although Darnold could return soon, Lock's strong performances have created renewed attention around his football cards.
Collectors are responding to the possibility that Lock could receive another starting opportunity, either with Seattle or elsewhere in the NFL.
Major Card Trends:
-
2019 Donruss Base Rookie (PSA 10): under $12 → $26

Lock's cards remain relatively affordable compared with many modern quarterback markets, but the recent percentage increases have been significant.
3. Ethan Salas
Ethan Salas of the San Diego Padres takes the number three position after receiving his long-awaited major league opportunity. One of baseball's most highly regarded catching prospects, Salas was the No. 1 prospect in the Padres' system before San Diego called him up on September 1st. At just 20 years old, his promotion has generated significant attention among baseball card collectors.
Salas has experienced some early struggles at the plate, hitting .167 through his first 30 major league at-bats. However, he has already shown flashes of his offensive potential, including his first major league home run as part of a two-hit, three-RBI performance against the Rockies.
Before his promotion, Salas was hitting .326 in Triple-A. That previous production, combined with his prospect pedigree and major league opportunity, has helped push his card market higher.
Notable Price Trends:
-
2023 Bowman Chrome Prospects 1st (PSA 10): $40 → $66
-
2023 Bowman Chrome Prospect Auto 1st (PSA 10): around $260 → $300
-

Salas' cards are benefiting from the increased exposure that comes with reaching the major leagues, while collectors continue watching for his offensive production to translate at the highest level.
2. Bryce Young
Bryce Young of the Carolina Panthers claims the number two position after opening his fourth NFL season with impressive statistical production.
The former No. 1 overall pick has thrown for 648 yards and six touchdowns through two games while also adding a rushing touchdown. After experiencing significant ups and downs during his first seasons in the NFL, Young's strong start has renewed attention around his football card market.
His recent performances have translated into substantial movement across several of his most recognizable rookie cards, including premium Kaboom and Downtown releases.
Key Card Movements:
-
2023 Absolute Kaboom Horizontal Rookie (PSA 10): under $1,000 → $1,450-$1,500

The gains across Young's cards demonstrate how quickly a strong start from a former No. 1 overall pick can reignite collector interest.
1. Tyler Shough
Tyler Shough of the New Orleans Saints takes the number one spot after emerging as one of the NFL's early breakout quarterback stories.
Shough nearly led New Orleans to a comeback against Detroit in Week 1 before completing the job in Week 2 against Baltimore. The Saints defeated Baltimore on the road, with Shough delivering an impressive performance. He completed 27 of 34 passes for 252 yards and a touchdown while also scoring the game-winning touchdown on a one-yard quarterback scramble with 1:28 remaining.
The comeback victory has generated substantial momentum around Shough's football cards, with several of his 2025 rookie releases recording significant increases over the past several weeks.
Major Card Trends:

2025 Donruss Downtown SSP Rookie (PSA 10): $715 → $1,150
