Collectible coins, particularly those from the United States, encompass a wide range of denominations, including the 1 cent (1c) and 50 cent (50c) pieces. Mint sets, such as those produced in 1991 by the Philadelphia Mint, typically include uncirculated coins from each denomination minted during that year. These sets are sought after by collectors for their condition and historical significance, and they often feature iconic designs representing American culture and history.
