Leaf 2003 Baseball — Checklist & Parallels

The full 2003 Baseball Leaf checklist — 620 cards with 9 base parallels and 20 insert sets — plus the eBay item specifics that matter and how to list them fast.

Leaf 2003 Baseball parallels

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

• Green Throwback Logo /25
• Blue Press Proof /50
• Red Press Proof
• Beckett Samples Gold
• Beckett Samples Silver
• Chicago Collection Wrapper Redemption /5
• National Sports Collectors Convention /5
• National Sports Collectors Convention Red Press Proof 1/1
• Orange County /5

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.
