Collectible coins are items sought after by numismatists and collectors due to their historical significance, rarity, and artistic value. Within the context of the United States of America, the P10c refers to a ten-cent piece, often associated with specific designs or types. Patterns from 1870 are trial pieces struck in limited quantities to test new designs or concepts before official minting. These patterns can be highly desirable among collectors, as they represent unique variations that showcase the evolution of U.S. coinage.
