Collectible coins refer to currency pieces that are sought after by numismatists for their historical significance, rarity, or unique features. In the United States, collectible coins include various denominations, designs, and production errors. The "P 10" designation typically refers to a specific grade or classification in coin grading. Patterns are experimental coins created to test new designs or compositions before official minting; an example includes the 1884 Pattern coins, which were produced but never circulated, making them highly desirable among collectors.
