Collectible coins encompass a wide range of numismatic items, including rare coins, historical issues, and patterns. In the United States, one notable example is the 1866 pattern coins, which were trial pieces created to test new designs before mass production. Patterns often feature unique designs or modifications and are highly sought after by collectors due to their rarity and historical significance. The "P 2 1 2" designation may refer to a specific cataloging system or grading scale used by numismatists to identify and classify these coins.
