Old stamps become useful historical evidence only after they are identified and documented. First separate unused postage, used or cancelled stamps, and complete covers. Then record the exact issue and condition before deciding whether to mail, collect, sell or seek expert help.
Start with the object in front of you
| Object | Record first | Why it matters |
|---|---|---|
| Unused stamp | Issue, denomination, gum, hinge, centering, perforations and faults | May have postal value, collector value, or both |
| Used/cancelled stamp | Issue plus cancellation place and date | The postmark can add historical context |
| Cover or card | Keep stamp, markings, address side and contents together | The full postal route may matter more than a loose stamp |
Identification checklist
- Record country, inscriptions, denomination and subject.
- Look for a date, series name or catalog match; the picture alone is often insufficient.
- Note format, perforations, paper, watermark or tagging where relevant.
- Photograph front and back in neutral light before handling further.
- Describe condition without optimistic labels: include creases, tears, thins, stains, missing perforations or disturbed gum.

Build a collection with a defined scope
Choose a boundary such as one issue, era, service, topic, printing method, state postal history or cover type. Use a consistent inventory with catalog reference, acquisition source, condition notes and photographs. A narrow, documented collection is easier to research than unrelated lots purchased because they were labeled “rare.”
Storage basics
- Use archival, stamp-safe mounts or stock pages and clean, dry handling tools.
- Avoid tape, glue, lamination, PVC storage, direct sunlight and uncontrolled humidity.
- Do not detach a stamp from a cover merely to fit an album.
- Keep provenance, certificates and purchase records with the item.
Postal use versus collector interest
Many genuine unused U. S. stamps issued since 1860 remain valid at their stated amount, but postal validity does not establish rarity or authenticity. Before mailing a potentially collectible stamp, compare the small amount of postage it pays with the evidence that would be lost when it is cancelled.
When to seek expertization
Professional help is appropriate when the exact identification depends on a scarce variety, overprint, grill, watermark, color, repair or suspected alteration—or when a meaningful transaction depends on authenticity. No photograph-only guide can certify the item.
