If you’re into rainbow collecting, Topps just announced one of the longest plays the hobby’s seen yet—and it kicks off this week.
As part of the 2025 Topps Chrome Baseball release, a brand-new insert set called “Cooperstown Calls” is making its debut. What makes it unique? Completing the full rainbow will take six years—and that’s the best-case scenario.
The concept centers around Hall of Fame inductees, with a single new, lower-numbered version dropping annually. This year’s release features the Blue (/150) card for the most recent Hall of Fame class.

From there, the chase continues year by year for those same inductees:
2026: Green (/99)
2027: Gold (/50)
2028: Orange (/25)
2029: Black (/10)
2030: Red (/5)
2031: Superfractor (1/1)
That’s right—the 1/1 Superfractor won’t hit packs until 2031.

This year, “Cooperstown Calls” will celebrate the 2025 inductees: Ichiro Suzuki, CC Sabathia, Billy Wagner, Dave Parker, and the late Dick Allen.
The idea builds on the long-running obsession with rainbow collecting—a phenomenon that’s exploded in the ultra-modern era.
While there’s no universal rulebook, many collectors aim to assemble every version of a card, with a true rainbow typically including a 1/1.
This latest Topps subset offers rainbow collectors a long-term chase.
