Topps High Tek 2018 Baseball — Checklist & Parallels

The full 2018 Baseball Topps High Tek checklist — 1148 cards with 6 base parallels and 21 insert sets — plus the eBay item specifics that matter and how to list them fast.

Topps High Tek 2018 Baseball parallels

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

• Black Rainbow Foil /50
• Blue Rainbow Foil /150
• Gold Rainbow Foil /1
• Green Rainbow Foil /99
• Orange Rainbow Foil /25
• Red Rainbow Foil /10

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.
