Collectible coins, such as the United States 25-cent coins from 1976, are sought after by numismatists for their historical and monetary value. The Philadelphia Mint produced commemorative quarters during this year, celebrating the United States Bicentennial. Mint sets include uncirculated coins produced specifically for collectors, preserving original quality and shine. The 1976 25-cent coin features a unique reverse design of Independence Hall, making it particularly desirable in completion of set collections.
