Fleer Showcase 2003 Baseball parallels

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

• Legacy /150
• Masterpiece 1/1

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.
