Collectible coins refer to coins that are sought after by collectors for their rarity, historical significance, or unique features. In the United States, collectible coins include various denominations, such as the 1 cent coin (penny), which has been produced in different styles and mintmarks over the years. Mint sets, like those produced in 1973 by the Philadelphia Mint, typically consist of uncirculated coins from that year, showcasing the current designs and providing a complete representation of the coinage issued. These sets are popular among collectors for their pristine condition and potential investment value.
