2026 Topps The National Sports Collectors Convention Collection MLB Baseball Hobby Box

2026 Topps National Sports Collectors Convention Collection is a show-only release created for the National Sports Collectors Convention, built as six dedicated boxes — MLB, NBA, Football, WWE, Star Wars, and UEFA — each with its own National Refractors base set, autographs, and parallels, and each card carrying the NSCC logo. The MLB box runs across the Prospects and Veterans & Rookies checklists with subjects like Mike Trout, Aaron Judge, and Jac Caglianone; the NBA box features Victor Wembanyama, Cooper Flagg, and Kon Knueppel; the Football box pairs NFL veterans and rookies — Caleb Williams, Drake Maye — with a Bowman U college subset; and the UEFA box highlights players including Estêvão Willian and Lennart Karl. The 2026 Topps National Sports Collectors Convention Collection checklist also covers dedicated Star Wars and WWE releases. Every box is a Blaster: 4 packs per box, 4 National Refractor cards per pack, with 2 parallels per box.
