Collectible coins, specifically the United States 25-cent quarter, include a series known as the State and Territorial Quarters. This series was issued from 1999 to 2008, featuring designs that represent each of the 50 states and U.S. territories. Each coin showcases a unique image that reflects the state's heritage, history, or significant landmarks. These quarters were part of a broader initiative to promote coin collecting and raise public interest in the U.S. Mint's coinage. The series is popular among collectors due to its variety and the cultural significance of the designs.
