2024 Leaf Trinity Mega Box Baseball Offers a Focused Build With Big-Time Hits

Leaf is keeping things tight with its 2024 Trinity Mega Box Baseball release, sticking to a smaller checklist and clear structure that still delivers plenty of excitement for collectors. Instead of loading the product with endless insert sets, this one focuses on a base set, a relic lineup, and the always popular Steel cards.


Each 10-card box is built around consistency. Collectors will find seven base cards, one Rookie Relics card, and two Steel cards. While the configuration is simple, the chase lies in the variations. Steel cards feature every player from the base checklist and come in 60 different styles, ranging from serial-numbered Silver cards out of 290 to multiple red and gold one-of-ones.


The 99-card base set mixes eras and talent levels, with legends like Ken Griffey Jr., Rickey Henderson, Pete Rose, and Vin Scully alongside today’s young stars such as Dylan Crews and Nick Kurtz. Rising prospects like Druw Jones, Travis Bazzana, and Charlie Condon are also part of the mix. With seven base cards per box, putting together the full set is manageable.


Rookie Relics expand the checklist with 67 featured players, highlighted by top names including Jesus Made. The Steel variations add another level of chase with foil finishes such as Lava, Lazer, Stars and Dots, Checkerboard, Donut Circles, and Shimmer, making the parallels stand out visually as much as statistically.


Key details collectors should know:


Cards per pack: 10
Packs per box: 1
Boxes per case: 20
Total base cards: 99
Release date: August 29, 2025


A typical box delivers two Steel cards, one Rookie Relics memorabilia card, and seven base cards, giving this product a streamlined but hit-heavy configuration.
