SECTION 1. SHORT TITLE.

    This Act may be cited as the ``Tomb of the Unknown Soldier 
Centennial Commemorative Coin Act''.

SEC. 2. FINDINGS.

    Congress finds the following:
            (1) The Tomb of the Unknown Soldier is a memorial site at 
        Arlington National Cemetery. On March 4, 1921, Congress 
        approved the burial of an unidentified soldier of the United 
        States on the site to commemorate the unknown soldiers who died 
        during World War I.
            (2) As of the date of enactment of this Act, the site also 
        includes unknown soldiers from World War II and the Korean War. 
        These graves are marked with white marble slabs embedded in the 
        plaza below the original sarcophagus.
            (3) The original white marble sarcophagus of the unknown 
        soldier from World War I features 3 Greek figures representing 
        peace, victory, and valor. There are 6 wreaths, 3 sculpted on 
        each side, which represent the major campaigns of World War I.
            (4) The original unknown soldier lay in the rotunda of the 
        Capitol from his arrival in the United States until Armistice 
        Day, 1921. President Warren G. Harding officiated at the 
        interment ceremonies at the Memorial Amphitheater at Arlington 
        National Cemetery.
            (5) The Tomb of the Unknown Soldier is guarded 24 hours a 
        day, 365 days a year, and in any weather by Tomb Guard 
        sentinels. The sentinels, all of whom are volunteers, are 
        considered to be the best of the elite 3d Infantry Regiment of 
        the Army (commonly known as the ``Old Guard''), headquartered 
        at Fort Myer, Virginia.
            (6) Inscribed on the back of the Tomb of the Unknown 
        Soldier are the words, ``Here rests in honored glory an 
        American soldier known but to God''.
