Sports Card Centering Guide

Border measurements, image alignment, issue-specific layouts and optical illusions.

Graded cards combine a physical collectible, a third-party opinion, a holder and a market premium. Each part deserves separate verification.

1. Measure borders

Measure borders should be evaluated against the exact card, issue, grading company, grade, qualifier and holder generation. Use official verification and recent completed sales rather than relying on label familiarity alone.

2. Check front and back

Check front and back should be evaluated against the exact card, issue, grading company, grade, qualifier and holder generation. Use official verification and recent completed sales rather than relying on label familiarity alone.

3. Account for design

Account for design should be evaluated against the exact card, issue, grading company, grade, qualifier and holder generation. Use official verification and recent completed sales rather than relying on label familiarity alone.

4. Do not rely on one photo

Do not rely on one photo should be evaluated against the exact card, issue, grading company, grade, qualifier and holder generation. Use official verification and recent completed sales rather than relying on label familiarity alone.

5. Use company standards

Use company standards should be evaluated against the exact card, issue, grading company, grade, qualifier and holder generation. Use official verification and recent completed sales rather than relying on label familiarity alone.

Verification rule: Never buy an expensive slab only because its certification number returns a valid result. Compare the physical item with the official record.
