Collectible coins are often categorized into several types, including patterns, which are experimental designs produced for testing before a coin is officially minted. The 1865 patterns from the United States feature unique designs that were never released for circulation, making them highly sought after by collectors. These coins typically showcase innovative artistic features and different compositions, reflecting the era's numismatic innovations. Collectors value these patterns for their historical significance and rarity, often resulting in high market prices at auctions.
