Collectible coins, particularly patterns, are experimental designs created for potential coinage that were not officially issued for circulation. The 1874 patterns from the United States feature various design aspects that were tested before the final designs were selected. These coins are highly sought after by collectors due to their historical significance and rarity, often reflecting the evolving aesthetics and technological advancements in minting during that period. Patterns from this era can vary widely in design and composition, showcasing the mint's exploration of new ideas for American currency.
