The USA Half Dollar 1921 Alabama is a commemorative silver coin issued to celebrate the 100th anniversary of Alabama’s statehood (1819–1919, minted slightly later in 1921).

Struck in 90% silver, the obverse features portraits of William Bibb and Thomas Kilby, key figures in Alabama’s early history. The reverse depicts an eagle perched on the Alabama state shield, symbolizing strength and unity.

This coin is part of the classic U.S. commemorative series and is valued by collectors for its historical significance and limited mintage.
