Collectible coins are often categorized by their rarity, historical significance, and condition. In the United States, specific types of collectible coins include patterns, which are experimental pieces struck to test designs or compositions before official production. One notable example is the 1915 patterns, which were created as part of the American effort to evaluate new coinage options. These coins can be highly sought after by collectors due to their limited issuance and unique designs.
