The Fifteen-cent Prexie
Small packet use
Small packets sent to foreign countries were subject to a minimum postage rate of fifteen cents from July 1, 1940 to November 1, 1953. Prior to that interval, a packet weighing eight to ten ounces would have required postage of fifteen cents as well.
Small packets were also subject to fees for customs clearance and delivery at the receiving end. These were ten cents for customs and five cents for delivery from July 1, 1930 until May 15, 1957. The item illustrated bears a fifteen-cent Prexie to pay these fees. Normally, a postage due stamp would have been used.
