2019-S American Innovation $1 Classifying Stars (Rev Proof) (DE)

This striking dollar coin represents a celebration of pioneering American ingenuity, issued as part of a multi-year series honoring groundbreaking innovators and achievements from every state, territory, and the District of Columbia. Released in the chronological order of statehood, this particular issue highlights Delaware. It features a distinctive reverse proof finish, which flips the traditional appearance by showcasing frosted fields alongside highly polished design elements. The obverse presents a classic profile of the Statue of Liberty, accompanied by the national motto of trust and the face value. A small, stylized gear privy mark is also integrated into the front design. On the reverse, a dramatic silhouette of astronomer Annie Jump Cannon is set against a star-filled night sky, commemorating her monumental work in organizing the cosmos. The inscriptions on this side clearly identify the state of Delaware, her name, and her scientific legacy of classifying the stars. Crafted with outer layers of copper, zinc, manganese, and nickel bonded to a core of pure copper, the coin also utilizes its edge to carry vital details. Incused along the outer rim are the year 2019, the San Francisco mint mark, and the traditional motto signifying national unity.
