Topps Chrome Update 2021 Baseball — Checklist & Parallels

The full 2021 Baseball Topps Chrome Update checklist — 392 cards with 9 base parallels and 8 insert sets — plus the eBay item specifics that matter and how to list them fast.

Topps Chrome Update 2021 Baseball parallels

Parallels are the colored and serial-numbered versions of each base card. This checklist includes:

• Purple Refractor
• Refractor /250
• Blue Refractor /199
• X-Fractor /99
• Green Refractor /75
• Gold Refractor /50
• Red Refractor /25
• Printing Plate /1
• Superfractor /1

When you list, put the exact parallel name in both the title and the Parallel/Variety item specific — a "Silver" listed as just a base card gets buried under cheaper copies.
