Collectible coins include a wide range of numismatic items, such as commemorative pieces, bullion coins, and historical currency. In the United States, coins are minted in various denominations, including the 1 cent (1c) and 50 cent (50c) pieces. Mint sets, particularly those produced in 1991, consist of uncirculated coins packaged directly from the U.S. Mint, showcasing all denominations issued during that year. These sets are sought after by collectors for their pristine condition and are often valued for both their numismatic significance and investment potential.
