2017-Uncle Sam’s Hat Stamp Additional Ounce Postage Stamps

On February 18, 2017, in Mesa, AZ, the U.S. Postal Service issued the Uncle Sam’s Hat additional ounce rate stamp (Nondenominated priced at 21 cents), in one design. With the release of Uncle Sam’s Hat in 2017, the U.S. Postal Service celebrates one of our country’s most popular patriotic characters. The stamp features eight graphic top hats in Uncle Sam’s signature style, with red and white vertical stripes above a blue band with a white star and a gray brim. Beneath each hat is an oval shape representing a face, each in a different shade, meant to suggest the ethnic and racial diversity of the United States. Art director Antonio Alcalá designed the stamp. The words “ADDITIONAL OUNCE” on this stamp indicate its usage value. Like a Forever stamp, this stamp will always be valid for the rate printed on it.
