SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Panama Canal and Pan-Pacific 
Exhibition Centennial Celebration Act''.

SEC. 2. FINDINGS.

    The Congress finds the following:
            (1) The Panama Canal, which cuts across the Isthmus of 
        Panama, was built between 1890 and 1914. It was the world's 
        greatest engineering feat of its time and required a labor 
        force of almost 40,000.
            (2) President Theodore Roosevelt, recognizing the value of 
        a canal, led the United States in buying the equipment and 
        concession to build the canal for $40 million, and championed 
        the effort that overcame malaria and immense logistical 
        problems. The Canal opened on August 15, 1914--401 years after 
        Spanish explorer Vasco Nunez de Balboa first crossed Panama.
            (3) Stretching 51 miles, the Panama Canal connected the 
        Atlantic Ocean and the Pacific Ocean, saving sailors a 
        dangerous 8,000-mile journey around Cape Horn and through the 
        Straits of Magellan, and cutting in half the time previously 
        required to sail between the oceans.
            (4) The 1915 Panama-Pacific International Exposition was a 
        world's fair held in San Francisco, California. The Exposition 
        ran from February 20 until December 4, 1915.
            (5) The Exposition commemorated the completion of the 
        Panama Canal and the 400th anniversary of the discovery of the 
        Pacific Ocean by Balboa.
            (6) Congress authorized the United States Mint to issue 
        five different coins dated 1915 in connection with the Panama-
        Pacific International Exposition. The coins represent a high-
        water mark for American commemorative coins. Produced at the 
        San Francisco Mint, these were the first United States 
        commemorative coins to bear the motto ``In God We Trust'', and 
        included the silver Panama-Pacific half dollar and four gold 
        coins in denominations of one dollar, 2\1/2\ dollars, a 50-
        dollar round coin, and a unique 50-dollar octagonal coin.
            (7) The octagonal $50 gold piece was the largest coin 
        authorized by Congress, and the first minted since 1852 in a 
        shape other than round.
            (8) The United States should mark the centennial of this 
        important event in San Francisco and the monumental achievement 
        of the opening of the Panama Canal.
            (9) The proceeds from the surcharge on the sale of such 
        commemorative coins will assist in supporting the educational 
        programs of the San Francisco Museum and Historical Society.
