The United States State Quarters program, initiated in 1999, features a series of 50 quarter coins, each representing one of the U.S. states. The coins were issued in chronological order of statehood, with each design depicting a unique symbol or landmark associated with the state. Collectors often seek out these quarters for their artistic designs and as part of complete sets. The 25-cent quarters, also known as "Territorial Quarters," are popular among numismatists not only for their variety but also for their role in commemorating U.S. state history.
