Block of four United States 50-cent postage stamps featuring Susan B. Anthony, Scott #1051

The Susan B. Anthony 50-cent stamp was issued by the United States Postal Service on August 26, 1955, as part of the Liberty Issue series. This stamp honored the pioneering women's rights activist and suffragist who played a crucial role in the American women's suffrage movement in the late 19th and early 20th centuries. The stamp was designed by Charles R. Chickering and features a portrait of Anthony based on a photograph taken in her later years. This block of four stamps appeals to philatelists who specialize in U.S. definitive issues, women's history commemoratives, and Liberty Issue series collectors. The Susan B. Anthony stamp is particularly valued by collectors interested in social reform themes and prominent American historical figures. Such blocks are sought after for their historical significance in documenting the evolution of U.S. postal history and the recognition of women's contributions to American society.
