Collectible coins, particularly U.S. quarters, include a variety of types such as the State and Territorial Quarters series, issued from 1999 to 2008. These quarters celebrate each of the 50 states and several U.S. territories, featuring unique designs on the reverse side that represent their respective characteristics. The coins minted in 2008, specifically those produced in San Francisco, often carry a higher numismatic value due to their limited production and distinctive finish compared to standard circulation coins. Collectors seek these quarters for their historical significance and artistic designs.
