Collectible coins, particularly patterns, are experimental or trial pieces created by mints to test designs or manufacturing techniques before final production. The United States Mint produced various patterns throughout its history, with notable examples arising in the 1870s, including the 1870 P 20 cent piece. These patterns are highly sought after by collectors due to their rarity, historical significance, and the insight they provide into the minting processes of the era. Patterns can vary in design, composition, and dimensions, making them intriguing pieces for numismatics enthusiasts.
