Demand full scans, exact identity, condition disclosure, return terms, and certificate details.
Identification rule: record what is visible before assigning a catalog number or value.
What to record
- Front and back images.
- Catalog number and variety basis.
- Gum, hinge, cancel, faults, repairs, and expertization.
What commonly causes mistakes
- “Rare” without a catalog identity.
- Tiny or blurry back images.
- Certificates cropped away from identifying details.
A practical research sequence
- Research seller history.
- Compare sold examples.
- Ask specific condition questions.
- Save the listing and images.
Condition and value
Value depends on exact identity, condition, centering, gum or cancellation, faults, certification, demand, and a defensible comparison set. A famous design does not automatically make an individual example rare.
