The 7-cent Washington stamp was issued to pay multiple rates. It was the first United States 7-cent stamp issued since the 1870-1871 Issue 7-cent Stanton. The 7-cent Washington underwent four renditions, differentiated by a variety of papers, coils, watermarks, and perforations.
This stamp was commonly used with other denominations to fulfill large weight and foreign destination rates. By the time the last 7-cent Washington stamps were sold, more than 550 million had been issued.
