1/2 Dollar Maine Statehood Centennial

Maine was admitted to the Union in 1820 as part of the Missouri Compromise, a legislative bargain that admitted Missouri as a slave state simultaneously to preserve the sectional balance. Congress authorized the centennial half dollar in 1920, and the entire authorized mintage of 50,028 pieces was struck at Philadelphia in a single year — no branch mint issues exist for this type.

Most were sold directly to the Maine Centennial Commission at a premium over face value. Genuine circulation examples are essentially nonexistent.
