Collectible coins are often categorized into several types, including patterns, which are experimental pieces struck to test designs before official release. The 1867 patterns, specifically, refer to various trial coins from the United States featuring different designs and denominations. These coins usually have limited mintage and can be highly sought after by collectors due to their historical significance and rarity. The patterns from this era provide insight into the evolving design philosophies of the U.S. Mint.
