Collectible coins include various types such as numismatic coins, bullion coins, and commemorative coins, which may attract collectors due to their rarity, historical significance, or beauty. The United States has a rich history of coin minting, with denominations like the 1 cent coin (1c) being widely collected. Mint sets, like those from 2015, are specially packaged collections of coins issued by the U.S. Mint, typically including coins from the Philadelphia mint, often sought after by collectors for their pristine condition and completeness.
