    PHILATELIST'S VERDICT

    Philatelist

    Stamp Specialist

    Identification of Scott #C25 and the U.S. Navy postmark is confirmed by visible design elements and denomination, with uncertainty limited only to the specific naval station name due to postmark cutoff.

    KEY EVIDENCE

    • 1Three copies of Scott #C25 (6¢ carmine Transport issue, 1941) arranged in an L-configuration on the upper right corner.

    CONDITION & GRADE

    Fine (Postal Cover)

    Grading breakdown

    The three Scott #C25 adhesives retain bright carmine pigment and are tied by clear naval killer strikes; deduction stems from envelope edge wear and lower horizontal creasing.

    Condition

    The cover exhibits visible peripheral toning, horizontal creasing along the lower third, edge soft wear, and mild postal handling consistent with WWII wartime postal transit. The stamps display intact perfs on visible edges with the upper-right adhesive slightly overlapping the right margin of the envelope.
