The Eighteen-cent Prexie
Sheet stamp use
The rate for a non-local first class letter was three cents from July 6, 1932 until August 1, 1958, and the minimum fee for registry was fifteen cents from April 15, 1925 to March 26, 1944. Thus, from July 6, 1932 until March 26, 1944 the cost of a registered first-class letter was eighteen cents.
This registered cover was sent from La Junta, Colorado to Cincinnati, Ohio in 1939.
