Collectible coins, particularly patterns, are experimental pieces struck by mints to showcase new designs or concepts before official production. The United States saw notable patterns in 1867, including designs that were not adopted for circulation. These coins often feature unique motifs or denominations and are highly sought after by numismatists for their historical significance and rarity. The 1867 patterns reflect the evolving aesthetic and technological innovations of the time in American coinage.
