Patterns are experimental coin designs created to test new designs or compositions before official production. In 1872, the United States Mint produced several pattern coins, often made in small quantities, which are highly sought after by collectors due to their rarity and historical significance. These coins showcase variations in design, denomination, and metal content, reflecting the Mint's exploration of innovations in currency. Collectors often seek out 1872 patterns for their unique attributes and connection to the evolving landscape of American coinage.
