Topps Triple Threads 2021 Baseball — Checklist & Parallels

The full 2021 Baseball Topps Triple Threads checklist — 1574 cards with 11 base parallels and 33 insert sets — plus the eBay item specifics that matter and how to list them fast.

Topps Triple Threads 2021 Baseball parallels

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

• Amethyst /299
• Emerald /259
• Amber /199
• Aquamarine /150
• Tourmaline /125
• Gold /99
• Citrine /75
• Onyx /50
• Sapphire /25
• Printing Plate /1
• Ruby /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.
