The U.S. State Quarters program began in 1999, featuring unique designs for each state.
56 quarters were minted, including 5 territories and the District of Columbia.
Artists submitted designs, with final approval by the U.S. Treasury.
Notable artists include John Flanagan and William Cousins, who designed many obverses.
Each quarter's reverse celebrates a state's history, landmarks, or symbols.
The program aimed to educate the public and spark interest in coin collecting.
Designs were often chosen through state contests and public input.
The U.S. Mint also released collector's editions with special finishes.
The series concluded in 2008, but remains popular among numismatists.
