In the realm of collectible coins, patterns are experimental designs created by mints to test new motifs or technologies before official production. The United States Mint’s 1866 pattern coins, particularly the designs featuring various depictions of Liberty or the nation’s symbols, are notable examples of such trials. These coins, often struck in limited quantities, hold significant historical value and appeal to numismatists due to their rarity and unique designs.
