This collection honors America's patriotism. Coins in circulation during the war years of the Twentieth Century are mounted with U.S. Postage Stamps issued to honor America's valor. The historic coins are dedicated to the spirit of Liberty and include the Buffalo Nickel, two .900 Silver Mercury Dimes symbolizing liberty of thought, and the 1943 Steel Lincoln Penny, struck for one year only, when copper was needed for the war effort. The 12 coins and 8 stamps are matted and displayed in a black vinyl portfolio. Comes with a Certificate of Authenticity.
