Topps Definitive Collection 2018 Baseball — Checklist & Parallels

The full 2018 Baseball Topps Definitive Collection checklist — 871 cards with 4 base parallels and 21 insert sets — plus the eBay item specifics that matter and how to list them fast.

Topps Definitive Collection 2018 Baseball parallels

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

• Green
• Purple /10
• Red Tag /1
• Red Team Logo /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.
