Collectible coins encompass various types that are sought after by numismatists, including historical, commemorative, and bullion coins. In the United States, collectible coins range from colonial issues to modern releases, with significant interest in pre-1776 private and regional issues, such as the 1724 pine tree shilling. One notable example is the 1p One Penny, which represents currency from regions with historical ties to the U.S. These coins often carry a premium value due to their age, rarity, and historical significance.
