Now you can own this stamp with rare tagging omitted. Did you know a stamp missing its phosphorescent tagging is considered by many to be similar to a missing color error? The good news is that unlike some error stamps, untagged error stamps are affordable.
What is Phosphorescent Tagging and Why is it Important?
Tagging of U.S. stamps was introduced in 1963 with airmail stamp #C64a. It helps the U.S. Post Office use automation to move the mail at a lower cost. A virtually invisible phosphorescent material is applied either to stamp ink or paper, or to stamps after printing. This “taggant” causes each one to glow in shades of green (red on older airmails) for a moment after exposure to short-wave ultraviolet (UV) light. The afterglow makes it possible for facing-canceling machines to locate the stamp on the mail piece, and properly position it for automated cancellation and sorting.
Some stamps have been printed with and without tagging intentionally, but when tagging is omitted by accident, we collectors are treated to a scarce modern color error. Our stamp experts examined thousands of stamps to find these just for you. Now you can easily give your error collection a boost or explore this fascinating new area of collecting. Quantities are limited, so order your untagged error stamp right away.

The Bicentennial Series
The U.S. Bicentennial was a series of celebrations during the mid-1970s that commemorated the historic events leading to America’s independence from Great Britain.
The official events began on April 1, 1975, when the American Freedom Train departed Delaware to begin a 21-month, 25,338-mile tour of the 48 contiguous states. For more than a year, a wave of patriotism swept the nation as elaborate firework displays lit up skies across the U.S., an international fleet of tall-mast sailing ships gathered in New York City and Boston, and Queen Elizabeth made a state visit. The celebration culminated on July 4, 1976, with the 200th anniversary of the adoption of the Declaration of Independence.
The U.S.P.S. issued 113 commemorative stamps over a six-year period in honor of the U.S. bicentennial, beginning with the American Revolution Bicentennial Commission Emblem stamp (U.S. #1432). As a group, the Bicentennial Series chronicles one of our nation’s most important chapters, and remembers the events and patriots who made the U.S. a world model for liberty.
