Collectible coins often include varieties such as patterns, which are experimental or prototype coins created to test designs and compositions before official minting. The 1864 Patterns from the United States feature various designs, including the famous Indian Head cent and the two-cent piece. These coins are highly sought after by collectors due to their historical significance, rarity, and unique features that distinguish them from regular issue coins. Collectors often focus on the P 3 designation, relating to specific pattern classifications, which further increases their value and interest within numismatic circles.
