Collectible coins, particularly mint sets, refer to collections of coins that are issued by a mint at the same time and often from the same year. The United States Mint has produced annual mint sets since 1947, featuring uncirculated coins from various denominations, such as 1-cent (penny) to 50-cent (half dollar) coins. The 1989 Mint Set, for instance, includes coins from the Philadelphia Mint and showcases that year's designs, materials, and production quality, making it a popular choice among collectors interested in U.S. numismatics.
