The Seven-cent Prexie
The seven-cent Prexie features a likeness of Andrew Jackson who was in office between 1829 and 1837. The stamp design is based on a statue in the rotunda of the United States Capitol. Stamps were issued in sheet format only.
Seven-cent Prexies were first released August 4, 1938. A relatively modest total of 906,545,800 were issued until production was stopped in1957.
There were few solo uses for seven cent Prexies until the domestic air mail rate was set at seven cents per ounce on August 1, 1958. The same air mail rate applied to Canada and Mexico. While production of the stamps had been stopped a year before they were still being issued in 1958, and there were still supplies to be used up.
A very late use is shown on this international postcard.
Other solo uses involve surface mail to any UPU country with air in the United States from late 1946 until the middle of 1948, and the return receipt fee on otherwise free government or Pan American Union diplomatic mail from 1952 to mid- 1957.
Second class, transient rates could result in a seven-cent charge.
The third class rate for miscellaneous printed matter and small packages weighing between six and seven ounces was seven cents from 1949 to 1958. Also, the combination of two ounces or less third class mail with minimum insurance was seven cents from the beginning of 1949 until the end of 1956.
Bound printed matter could be sent for seven cents at various times. There are different weight and distance combinations involved as well.
Other fourth class uses were possible.
Some other solo uses exist, but are not at all common. One such that is possible for almost any denomination is to pay the business reply mail service fee. Another is to pay the charge for a certificate of mailing for multiple items.
