Collectible coins encompass various categories, including patterns, which are trial pieces created to test designs or compositions before mass production. In the United States, pattern coins are particularly significant, with the 1870s producing several noteworthy examples. The designation "P3C" refers to the third pattern coin produced by the U.S. Mint, further highlighting its rarity and significance among numismatics. Collectors value these coins not only for their artistic merit but also for their historical importance within American coinage.
