The 2011-S Silver Proof Set includes Superb 2011 Proof Examples Of All 4 Proof Presidential Dollars, All 5 Silver America the Beautiful Quarters, Lincoln Cent, Silver Jefferson Nickel, Silver Roosevelt Dime, Silver Kennedy Half and Proof Native American Dollar! The silver coins are struck in 90% silver - the same composition used since the early days of the the U.S. Mint. The blanks are fed into presses fitted with hand-polished dies and struck at least twice to ensure sharp relief. United States proof coins are extraordinarily brilliant, with sharp relief and a mirror-like background and packaged in presentation cases to showcase and maintain their exceptional finish. |
