P3C refers to the series of pattern coins struck in the United States, particularly a design created in 1865. These patterns were experimental coins that served to test new designs and denominations before official production. The 1865 patterns are significant due to their aesthetic and historical value, often attracting collectors interested in rare and unique pieces of numismatic history. The designs from this era illustrate the artistic trends and innovations in American coinage during the mid-19th century.
