Patterns are experimental coin designs created by mints to test various concepts, compositions, and aesthetic styles before final production. In the United States, one notable example is the 1865 Pattern coin, which originated from the Philadelphia Mint. These coins are often considered highly collectible due to their limited production, unique designs, and historical significance, attracting numismatists who value their rarity and innovation within the broader context of U.S. coinage.
