Collectible coins are valuable items sought after by numismatists and collectors, often based on age, rarity, condition, and historical significance. In the United States, collectible coins include various denominations, such as the One Dollar coins, which have featured a range of designs over the years. The Coronet Head Cent, introduced in 1832, is significant as it represents a transition in design and is a popular choice among collectors due to its historical context and limited mintage. Collectors often focus on specific types or eras, seeking to complete sets or acquire rare pieces for investment or personal enjoyment.
