The Nineteen-cent Prexie
The nineteenth President of the United States was Rutherford B. Hayes, who served from 1877 until 1881. The design forhis Prexie stamp was taken from a Presidential medal manufactured by the United States Mint. Nineteen-cent Prexies were only issued in sheet format.
Nineteen-cent Prexies were first issued on November 10, 1938. A total of 102, 662, 900 were issued from then through 1956.
There were very few solo uses of the nineteen-cent Prexie. Some possibilities were a double-weight drop letter with first step registry from July 1, 1932 until March 26, 1944, a double-weight special delivery letter from November 1, 1944 until the end of 1948, a special delivery airmail postcard from the first of 1949 until the end of 1951, and a special delivery letter from a member of the armed forces serving outside the United States, from November 1, 1944 until October 1, 1946.
Other possible solo uses include insured third class, parcel post and certificates of mailing.
