In 1976 the National League and National Association of Postmasters acting as the Postmasters of America commissioned The Franklin Mint to gather a collection of mint stamps commemorating US History. 200 stamps in Extremely Fine, Original Gum, and Never Hinged (XFnh) condition were selected and mailed to subscribers at a rate of six per month for nearly three years, later including an album binder to house the collection and finally in 1979 a certificate of authenticity (COA). The oldest event commemorated is Coronado’s expedition of 1540 with the three cent cuarto centennial stamp of 1940. The last event commemorated the creation of the Department of Energy in 1977 with a thirteen cent Energy Development stamp. The oldest stamp in the collection is a two cent stamp from 1929 commemorating the 150th anniversary of George Rogers Clark’s capture of Vincennes during the Revolutionary War. The newest stamps were part of the American Bicentennial commemorative collection from 1976 and 1977. Today, even the newest stamps in this collection are nearly fifty years old! The album has been stored for 47 years in a climate-controlled, smoke-free environment and has very slight indications of wear. Each stamp is sleeved in a protective jacket, then mounted to an acid-free descriptive narration card with individual artwork commissioned by the POM for the collection. Then each card is housed inside an album sleeve.
