This is a classic Great Britain 1d Red perforated stamp, issued in 1858 during the reign of Queen Victoria. The design features the left-facing profile of the Queen, based on William Wyon’s medallion portrait. The denomination “ONE PENNY” is inscribed at the bottom, and the stamp is printed in a distinctive red shade.

Your example shows the plate letters “J” (top left) and “A” (bottom right), which helped identify the printing position. The bold barred numeral cancellation “322” corresponds to the post office of Liverpool, one of the busiest hubs of Victorian Britain.

These stamps are highly collectible because they exist in many shades, plate numbers, and cancellation varieties. Collectors often specialize in studying postmarks like the Liverpool “322,” which adds postal history interest. Condition, centering, and clarity of the plate and postmark strongly influence value.
