United States Stamp Society
The United States Stamp Society (USSS) is the preeminent organization devoted to the study of United States stamps. It is, “a non-profit, volunteer-run association of collectors to promote the study of the philatelic output of the Bureau of Engraving and Printing and of postage and revenue stamped paper produced by others for use in the United States and U.S. administered areas.” Once concerned exclusively with the production of the Bureau of Engraving and Printing, the USSS has expanded its coverage to include all United States issues, both classic and modern, regardless of printer.
