Six-cent through Eleven-cent Prexies
Transient second-class use
Second-class, transient rates were one cent per each two ounces or fraction thereof from July 1, 1928 until April 1, 1952. The Life magazines from which the following illustrations were graphically cropped were sent from Chicago to Wichita in 1942, 1943 and 1945. They weighed various amounts, and the postage on all of them is consistent with second-class, transient charges.
Beecher/Wawrukiewicz says that the second-class, transient rate applied to mailings of eight ounces or less, with heavier items using the fourth-class rate. However, the weight limit on second-class, transient mail was removed in 1928.
Magazine sent in 1943. Weight of 11.8 ounces, rounded to 12, results in six cents postage at one cent per two ounces.
