Collectible coins, such as those from the United States of America, often include various denominations, including the 25-cent piece (quarter). Mint Sets are specially packaged collections of coins produced by the U.S. Mint, showcasing different denominations struck in a specific year. The 1976 Mint Sets are particularly notable as they include coins commemorating the United States Bicentennial, featuring unique designs and marks such as the depiction of the Liberty Bell superimposed on the moon for the quarter. These sets appeal to both numismatists and collectors due to their historical significance and varying mintages.
