#1358a – 1968 6c Arkansas River Navigation

U.S. #1358a Tagging Omitted
6¢ Arkansas River Navigation

Issue Date:  October 1, 1968
City:  Little Rock, AR
Printed By:  Bureau of Engraving and Printing
Printing Method: Lithographed, engraved
Perforations:  11
Color:  Bright blue, dark blue and black

This stamp was issued to celebrate the opening of the first portion of the Arkansas River to commercial navigation.  The system has 17 locks and dams.  Twelve of these are located in Arkansas and five in Oklahoma.  In 1971, an Act of Congress designated the official name of the waterway as the McClellan-Kerr Arkansas River Navigation System.  This name is commonly abbreviated as MKARNS.

The MKARNS system is made up of 445 river miles with a minimum water depth of nine feet.  Its benefits include: water supply, navigation, fish and wildlife conservation, recreation, hydroelectric generation, and flood control.  Over the past 30 years, the MKARNS has created 54,000 jobs, generating a payroll of over $1 billion.

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.
