Handling an Inherited Graded Card Collection

Inventory certification numbers, verify slabs and compare selling paths.

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

1. Photograph as found

Photograph as found 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. Verify each cert

Verify each cert 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. Flag stars and rookies

Flag stars and rookies 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. Preserve sets

Preserve sets 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. Compare offers

Compare offers 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.

Marketplace research

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