Collectible coins, particularly those from the United States, encompass a variety of types, including patterns, which are experimental or trial strikes made to test designs or technologies. One notable example is the 1874 patterns, which were created as part of a significant numismatic effort to refine coinage designs during that era. Patterns are typically produced in limited quantities and are often struck in different metals, making them highly sought after by collectors. The 1874 patterns include several denominations, each illustrating unique design features that distinguish them from regular circulating coins.
