Block of four 5-cent George Washington postage stamps, U.S. Postage

The 5-cent George Washington stamp was part of the regular issue series produced by the United States Postal Service from 1962 to 1966. This design featured a portrait of America's first president and was one of the most commonly used denominations during this period for standard letter mail. These stamps were printed in large quantities and saw widespread everyday use across the country. While common stamps hold modest value, collectors of U.S. postal history appreciate blocks and multiples for their visual appeal and historical significance. Stamp collectors, particularly those specializing in 20th-century U.S. definitives or presidential series, seek out well-preserved examples, plate blocks, and error varieties. The condition, centering, and presence of original gum significantly affect collectibility and value among philatelists.
