The set includes all five proof quarters issued under the 50 State Quarters« Program for 2002 and celebrates the unique heritage of the states:
- Tennessee "Musical Heritage"
- Ohio "Birthplace of Aviation Pioneers"
- Louisiana "Louisiana Purchase"

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.
