The 1918 Illinois Centennial Half Dollar is a historic coin that celebrates the 100th anniversary of Illinois joining the United States.
Often referred to as the “Lincoln-Illinois Half Dollar,” it prominently features President Abraham Lincoln on the front, paying tribute to one of the state’s most famous figures.
The Story Behind the Coin
This commemorative coin was introduced thanks to the efforts of the Illinois Centennial Commission. The group sought to create a special coin to fund centennial celebrations in Springfield and other parts of Illinois. Congress approved the idea, and the coin’s production was officially authorized on June 1, 1918.
The Philadelphia Mint produced 100,000 of these coins in August 1918, along with 58 additional coins for quality testing. These coins were initially sold through banks and the Springfield Chamber of Commerce at double their face value, helping fund the festivities.
The Coin’s Design
- Front (Obverse):
Abraham Lincoln is depicted without his iconic beard, his head slightly bowed in a thoughtful pose. The words “Centennial of the State of Illinois” curve along the top edge, while “In God We Trust” appears behind Lincoln’s head. The year 1918 is inscribed below. - Back (Reverse):
The reverse showcases an eagle standing on a rock with a shield, symbolizing Illinois’ strength and unity. The eagle holds a banner with the state motto, “State Sovereignty, National Union.” The sun rises in the background, surrounded by the words “United States of America” and “Half Dollar.”
Both sides of the coin reflect the detailed craftsmanship of the Mint’s top engravers. George T. Morgan, known for designing the Morgan Dollar, created the obverse, while John Sinnock designed the reverse, inspired by Illinois’ Great Seal.
