The U.S. Postal Service reversed itself Wednesday and announced that it won't destroy 300 million stamps, despite an error in the margin of the 100-stamp sheets honoring the late Hubert H. Humphrey.

The stamp will be released during June 3 ceremonies in Minneapolis.Postmaster General Anthony Frank's announcement reversed an initial decision to destroy the stamps and reprint them.

Frank said he decided to allow the stamp to be sold because there was no error on the stamp itself and reprinting it would have cost $580,000.

The error, which is in the margin - also called the selvage - of the sheets of 100 stamps, indicates that Humphrey was vice president from 1964 to 1968. He was elected in 1964, but took office in 1965 and served until 1969.
