The Eleven-cent Prexie
James Polk, president from 1845 to 1849, is pictured on the eleven-cent Prexie. This was his first appearance on a postage stamp. Eleven-cent Prexies were only issued in sheet format.
The first release of the eleven-cent value was on September 8, 1938. Only 618,689,700 were delivered through 1957.
The eleven-cent Prexie had virtually no single-rate solo use during the period it was issued. Second class, transient rates could result in a eleven-cent charge. Fourth class use for single piece bound printed matter of one pound or less to Zones 1 and 2 from 1951 to 1954 and to Zone 8 from 1944 to 1949 are possibilities, but rarely if ever seen.
Other solo uses are combinations of rates. The ones most often seen are the international surface letter rate for two to three ounces to a UPU country and the combined air-surface-air rate to Europe. Another possibilitiy is the rate for surface transport to Europe and then air to Egypt, the Sudan, or Palestine prior to late 1940.
The special delivery domestic postcard rate was eleven cents prior to late 1944. Fourth class parcel post service for more than one pound could also result in an eleven-cent charge. There were also combinations of airmail with minimum insurance that would produce the rate.
Shortly after the end of what is considered the Prexy period, 1960, several eleven-cent rates were established. One was the surface letter rate to UPU countries from July of 1961 to May of 1967, and the foreign airmail postcard rate during the same interval. It is unusual to see either of these uses paid with a Prexie, but that did happen.
A certificate of mailing for multiple items can result in any value of solo Prexie being used.
