Basketball Parallel Guide
Cosmic Chrome debuted in basketball in 2023-24 and returned in 2025-26 as a licensed NBA release. Its collector hierarchy runs through a 200-card base set, product-native Refractors, Planetary Pursuit, rare themed inserts, and separate signature programs.
Topps does not state a serial for the 2025-26 First Day Issue or either plain Refractor in the two core autograph-variation families. Lunar /10 remains an inference from the wider Cosmic Lunar convention, not a serial stated on the basketball odds sheet.

Aqua moves to /199, Purple Nebula enters at /150, and the familiar Blue-to-SuperFractor ladder returns. FDI has an official 1:662 Hobby odd but no stated serial; Lunar /10 is inferred, so neither should borrow certainty from its name.
