Collectible coins include a variety of types, with patterns being a specific category that features unique designs or test strikes not intended for circulation. The United States has produced several notable collectible coins, including the 1861 pattern coins. These patterns were made for testing purposes and often feature distinct modifications from their circulating counterparts, making them highly sought after by collectors. The "P" mintmark indicates coins produced at the Philadelphia Mint, and the "10" may refer to denominations or specific features related to particular coins in this context.
