Vintage Sports Cards

What to record

Record the year, set, subject, card number, parallel or variation, language, grading company, numerical grade and certification number. Photograph the front, back, label, seams and any holder damage.

Category-specific checks

• Creases, paper loss, trimming and restoration require special attention.
• Lower numerical grades can still be desirable when the issue is scarce.
• Registration and factory cut can complicate centering judgments.

How to compare sales

Use completed transactions for the same card, grading company and grade. Separate best-offer listings, auctions, bundled lots, mislabeled cards and outliers. Population data can add context, but it is not a count of cards available for sale.
