Collectible coins, such as patterns, are experimental or test coins that were often produced by mints to assess design or manufacturing techniques. The 1869 P3C patterns from the United States feature unique designs that differ from standard coins, making them highly sought after by collectors. These patterns were typically not released for general circulation and often provide insight into the minting processes of the era. Their rarity and historical significance contribute to their value in the numismatic market.
