Topps Opening Day 2018 Baseball — Checklist & Parallels

The full 2018 Baseball Topps Opening Day checklist — 909 cards with 5 base parallels and 19 insert sets — plus the eBay item specifics that matter and how to list them fast.

Topps Opening Day 2018 Baseball parallels

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

• Printing Plates Black /1
• Printing Plates Cyan /1
• Printing Plates Magenta /1
• Printing Plates Yellow /1
• Purple

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.
