The 10-coin United States Mint Proof Set®, is the fifth annual set in the ten-year series celebrating each of the 50 states in the order in which they entered the Union. Few coins today have the degree of artistry and detail that is so beautifully revealed in a proof coin. The set includes all five 50 State Quarters issued in 2003 in proof condition - Illinois, Land of Lincoln, Alabama, Spirit of Courage, Maine, Pemaquid Point Light, Missouri, Corps of Discovery and Arkansas, Natural Resources. The set also includes proof versions of the Lincoln cent, the Jefferson nickel, the Roosevelt dime, the Kennedy half dollar and the Golden Dollar featuring Sacagawea.

United States proof coins are extraordinarily brilliant with a sharp relief and a mirror-like background. Their frosted, sculpted foreground gives them a special "cameo" effect, created by the proofing process. Proof blanks are specially treated, polished, and cleaned to ensure high-quality strikes. The blanks are then fed into presses fitted with hand-polished dies and struck at least twice to ensure a sharp, high relief. The coins are then packaged in presentation cases to showcase and maintain their exceptional finish.
