The 9-cent Franklin, the first 9-cent stamp issued by the U.S., was issued to pay multiple rates. It underwent four renditions, differentiated by a variety of papers, coils, watermarks, and perforations.
The 9-cent Franklin stamp was commonly combined with other denominations to fulfill large weight and foreign destination rates. By the time the last 9-cent Franklin stamps were sold, more than 300 million had been issued.
