Graded-card guide

Minimum Grade, Review and Crossover Submissions

How minimum grades, holder reviews and crossovers affect cost and risk.

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

1. Read service terms

Read service terms 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. Choose minimum carefully

Choose minimum carefully 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 fees

Account for fees 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 assume crossover success

Do not assume crossover success 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.
