The Post Office Department issued the first 15-cent Franklin in February 1912. It appeared in four renditions throughout its years of use. A variety of papers, coils, watermarks, and perforations differentiate one version from another.
As a single stamp, the 15-cent Franklin could have paid the three-times weight of the Universal Postal Union international rate. In addition, patrons often combined it with other denominations to fulfill large weight and foreign destination rates. By the time the last 15-cent Franklin stamps were sold, more than 382 million had been issued.
