2025 Panini Boys of Summer Baseball Checklist

Pack odds: none of the three sources publishes an odds sheet, so nothing here is an estimate.

Base Crusade (200 cards), the Call To Arms, Certified Stars, Certified Team Gold, Crusade Blue, Heating Up, Knightcap, Numbers, Certified Prospects, Juggernauts and Spirit Of The Game inserts, Tools Of The Trade Swatches and the Crusade, Perennial Prospect, Past Time and Majestic Marks signature sets: Cardsmiths lists them but ChecklistInsider and BaseballCardPedia do not, so no second source confirms them.

Massive Materials Holo Gold run: ChecklistInsider prints /10 while Cardsmiths and BaseballCardPedia print /5, so the rung is left out; the Platinum 1/1 is shown.

Red parallel on America's Best, American Glory, Fan Favorites and Prospect Material Signatures: ChecklistInsider prints /75 or /49 and Cardsmiths /75, so the run is left out; the Holo Silver, Holo Gold, Emerald and Platinum rungs are shown.

Individual print runs on each autograph and Fabric of the Game card: ChecklistInsider tags cards one by one, Cardsmiths publishes only the ladder, so the per-card runs are not carried.

Rookie (RC) logos: only Cardsmiths flags them, so no row carries an RC mark.

Holo Silver availability by card (BaseballCardPedia notes some Pastime, Five Tool and Jumbo Prospect cards have no Holo Silver version): the other sources do not list the exceptions, so the ladders are shown as printed.

Team on cards where the sources print a former club or an amateur team (for example Homestead Grays, High School, college teams) is shown as both sources print it; no current-franchise mapping is added.
