This was the 1915-S Panama Pacific Half Dollar, which represented only the second commemorative half dollar from the United States Mint. The half dollar was issued in conjunction with the Panama Pacific Exposition held that year in San Francisco. Several other commemorative coins were issued for the occasion including a gold dollar, a quarter eagle, and two $50 gold pieces. The Panama Pacific Half Dollar is considered to be one of the most attractive classic commemorative half dollars and has been popular since the exposition.
