Collectible coins, also known as numismatic coins, include a variety of types such as circulated coins, uncirculated coins, and proof coins. In the United States, coins are often categorized by denomination, including common denominations like the 1 cent (1c) and 50 cent (50c) coins. Proof sets, such as the 1994 Proof Set, are specially minted coins characterized by their high-quality finish and often include the entire annual coinage for that year. Collectors often seek these items for their aesthetic appeal, historical significance, and potential for value appreciation over time.
