Preserve organization before assuming the collection is either worthless or a fortune.
Identification rule: record what is visible before assigning a catalog number or value.
What to record
- Albums, stockbooks, covers, certificates, dealer cards, receipts, and notes.
- Areas where the collector spent specialized effort.
- Material stored separately or in a safe.
What commonly causes mistakes
- Removing stamps from pages destroys organization.
- Throwing away covers can erase postal-history value.
- Internet asking prices create false expectations.
A practical research sequence
- Photograph shelves and album labels.
- Create a box-level inventory.
- Separate certificates and obvious high-value items without rearranging them.
- Seek society, dealer, auction, or appraisal guidance appropriate to the material.
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.

Use listings to study descriptions, scans, certificates, and market supply. Asking prices are not completed-sale evidence.
