Never before have so many sacrificed so much. The 65 million men who were mobilized for military service during World War I are honored with our collection of true rarities. It begins with a Lincoln Wheat penny, a Buffalo nickel and a silver Mercury dime, all struck in the war years of 1914 to 1918. Three US postage stamps complete the set: the 8 cent General John J. Pershing released in 1961, the 22 cent Veterans World War I, 1985, and the 3 cent "Win the War" Victory Stamp, 1942. Certificate of Authenticity included.
