In 1997, Congress passed the 50 States Commemorative Coin Program Act, which instructed the creation of the 50 State quarters series to "honor the unique Federal Republic of 50 States that comprise the United States; and to promote the diffusion of knowledge among the youth of the United States about the individual states, their history and geography, and the rich diversity of the national heritage...", and to encourage "young people and their families to collect memorable tokens of all of the States for the face value of the coins."
