July Rookie Risers: Misiorowski's 149 Percent Spike and the Crow-Armstrong Surge Before All-Star Week
Jacob Misiorowski's 1st Bowman auto in PSA 10 is up roughly 149 percent and Pete Crow-Armstrong's monster June has his chrome rookies setting new highs. Here is who is moving, why All-Star week matters, and how to play a hot streak without overpaying.
The Rookies Moving the Market Right Now
The first full week of July has produced some of the sharpest rookie card price action of the season, led by a pair of National League breakouts that graded-card buyers are chasing hard into All-Star week.
Jacob Misiorowski: The Fastest Riser in Baseball
The Brewers flamethrower has turned triple-digit velocity into triple-digit card gains. His 1st Bowman Chrome autograph in PSA 10 has jumped roughly 149 percent, one of the steepest 30-day moves of any modern baseball card. Pitcher cards are historically volatile, but Misiorowski's strikeout numbers and highlight-reel fastballs have made him the hobby's favorite arm of the summer.
Pete Crow-Armstrong: A June for the Ages
The Cubs center fielder hit .381 with 11 home runs and a 1.249 OPS in June, and his cards have followed. His rookie-year Topps Chrome and Bowman Chrome autos have been among the most traded modern baseball cards on eBay over the past two weeks, with graded 10s setting new highs almost nightly.
Why the Timing Matters
All-Star Week Is a Price Catalyst
MLB All-Star week in Philadelphia lands July 13-15, and All-Star selections reliably produce short-term price pops, especially for first-time selections. Both players are in the conversation, and Home Run Derby participants historically get an extra bump.
New Product Keeps Feeding the Fire
With 2026 Topps Finest out this week and 2026 Topps Chrome landing July 22, there is a steady supply of fresh rookie chrome hitting the market. That cuts both ways: new pulls add supply, but big releases also concentrate hobby attention on exactly these names.
How to Play a Hot Streak
- Selling into strength beats buying it: a 149 percent 30-day move prices in a lot of future performance.
- Pitchers carry extra risk: injury exposure makes arms the most volatile rookie class in the hobby.
- Watch the population reports: fresh submissions of hot rookies grow PSA 10 populations quickly, which can soften prices even while raw demand stays strong.
If you are hunting these cards in person, check your local card shop's case before paying eBay comps. Shop pricing often lags fast movers by a week or more, in both directions.
