Collectible coins include various types such as patterns, which are experimental or prototype coins struck to test designs before final production. In the United States, the 1860 pattern coins are notable examples, showcasing innovative designs that may not have been widely circulated. They were often produced in limited quantities, making them highly sought after by collectors. The P50c designation refers specifically to a 50-cent piece, and coins from this era, including patterns, are valued for their historical significance and rarity.
