2026 Topps Series 1 Baseball Hobby Jumbo Box

2026 Topps Series 1 Baseball Hobby Jumbo Box celebrates the 75th Anniversary of Topps Baseball with a flagship checklist featuring current stars, rookies, Future Stars, league leaders, team cards, inserts, autographs, relics, and anniversary-themed parallels. Each Jumbo Hobby Box includes 10 packs with 40 cards per pack, plus 2 promo packs, and delivers 1 autograph and 1 relic card per box. This is the larger-format hobby option for collectors who want more cards, stronger hit content, and a deeper rip from the 2026 flagship release.
