- Centering — the alignment of the design within the perforations
- Gum Condition — original gum integrity, hinging, and disturbances
- Perforations — completeness, evenness, and any missing or short perfs
- Paper Quality — thins, tears, creases, stains, or faults
- Color & Impression — vibrancy, freshness, and print clarity
Why Get Your Stamps Graded?
A professionally graded stamp is encapsulated in a protective holder that preserves its condition and authenticates its grade. PCAGC certification increases the marketability and value of your stamps, giving buyers the assurance they need and helping sellers achieve the best possible results.
