2026 Topps Celebration Series 1 Baseball adds a little extra fun to the flagship MLB lineup by way of multiple exclusives.
Mega Box presales ($49.99) first appeared on the Topps website on February 23, 2026.
Although the price is the same as last year, there are two fewer packs per box.
2026 Topps Celebration Series 1 Baseball Checklist Rundown
Just like the 2025 edition, the 2026 Topps Celebration Series 1 Baseball checklist features standard flagship cards alongside exclusives available only in this Mega Box format.
Look for the Opening Day foil editions of the base set, plus colorful Confetti parallels.
The boxes also include exclusive inserts, some of which utilize the base design. Dugout Peeks offers off-field images of top players.
Walk This Way takes a more celebratory approach.
Fans can also find the beloved furry creatures in the Mascots set.
Gameday Drip is one of the more striking options, seemingly oozing with gold and gems.
