U.S. Mail One Cent Prepaid Stamp - Historical Postal Marking #105 (License: Personal Use)

This black-ink circular handstamp reads “U.S. MAIL” along the outer ring, “ONE CENT” in the center, and “PREPAID” along the lower arc-a common marking applied by post offices to confirm postage was paid before mailing. The slightly irregular edges and bold serif type reflect the manual stamping process of the mid-to-late 1800s. Such marks were essential for efficient sorting and revenue tracking in the pre-adhesive-stamp era.

Used on historical mail documents, philatelic exhibits, or educational content about U.S. postal history; targets collectors, historians, and educators seeking authentic imagery of early postal practices.
