2025/26 Topps Signature Class Basketball Mega Box

Cooper Flagg's first-ever NBA-licensed Topps auto is here — and it lives inside the 2025/26 Topps Signature Class Basketball Mega Box, the NBA debut of a brand built entirely around the art of the signature.

Configuration: 8 cards per pack, 10 packs per box, with 2 Chrome exclusive parallels guaranteed per box. Look for the retail-exclusive SP Odyssey insert alongside autographs and numbered parallels in every box.

The product starts with a 150-card base set that includes 50 rookies. Every card shows two photos alongside each player's draft round and pick number, available in both paper and Chrome, each with a full parallel rainbow. The checklist includes top rookies like Cooper Flagg, Dylan Harper, Ace Bailey, and Derik Queen, alongside global icons such as Stephen Curry, LeBron James, Victor Wembanyama, Anthony Edwards, and Shai Gilgeous-Alexander.

Autographs are headlined by Chrome Autographs and Crystal Clear Autographs, alongside signature-driven subsets including Signature Blend, Shadow Scripts, Manuscripts, and Eternal Marks. The Crystal Clear Autographs series features NBA rookies, stars, and legends on acetate stock.

Veteran Class paper parallels run Magenta #/250 → Teal #/225 → Indigo #/175 → Green #/150 → Purple #/100 → Pink #/75 → Orange #/50 → Red #/25 → Red Lava #/25 → Black #/10 → Black Gold #/10 → Blue #/5 → Foilfractor #/1, while Rookie Class adds Yellow #/399 and Coral #/299 at the entry tier.

What you're hunting:

• Cooper Flagg / Dylan Harper Dual Auto — the two phenoms paired on one card
• SGA / Jalen Williams / Chet Holmgren Triple Auto — OKC's title-winning Big Three on a single card
• Chrome Veteran Auto parallels: Orange #/50, Red #/25, Gold #/10, Blue #/5, Superfractor 1/1 (odds: 1:308,125 Mega)
• Aristocrats and Pressure Points — retail-exclusive case hits
• Odyssey SP inserts — retail exclusive short prints
• Roses insert — acetate-stock cards giving legends like Magic Johnson, Shaquille O'Neal, and Derrick Rose their flowers
• Veteran Chrome Auto Superfractor 1/1 and Blue #/5 across a 46-card signed checklist

This is the NBA's debut version of the Signature Class brand — Topps has expanded a blossoming product line across sporting lines to showcase the NBA's best in this autograph-driven set. Adding veterans like LeBron, Curry, and Olajuwon to the auto checklist gives the product staying power a rookie-only release wouldn't have. The Mega Box is the sharpest retail entry point into the most talked-about new NBA brand of 2026 — get in before the secondary market catches up.
