The U.S. Mint has unveiled its commemorative silver dollar marking the centennial of American involvement in World War I. The collectible coin will be available for purchase from the Mint in January. A portion of the proceeds will go toward construction of the new National World War I Memorial at Pershing Park, a block from the White House. This is the Mint’s first commemorative coin program memorializing the Great War. Read more about the WWI Commemorative Coin on the U.S. WWI Centennial Commission website.
