In the realm of collectible coins, patterns refer to coins that were struck for testing or design purposes, often produced in small quantities and not intended for general circulation. The United States' 1861 Pattern coins are particularly notable as they were created during a tumultuous period in U.S. history, reflecting design changes and innovations in minting. The "P 5" designation likely pertains to a specific pattern coin, potentially a five-cent piece, showcasing the unique artistic vision and historical significance of that era. Collectors seek these pieces for their rarity and connection to U.S. numismatic history.
