Collectible coins encompass a wide range of numismatic items, including historical coins, commemorative pieces, and currency with unique features or low mintage. The One Cent Penny, a staple in American coinage, has undergone various design changes since its inception in 1793, with notable types including the Lincoln penny. Early Washington pieces, minted from 1792 to 1795, represent the early efforts of the United States to establish its own currency and often hold significant historical value. The term "Unknown" may refer to varieties or specific examples that lack comprehensive documentation in numismatic records, which can enhance the interest and value for collectors.
