History of the 1918 Illinois Centennial Half Dollar
Background and Purpose
The Illinois Centennial Commission wanted a special coin to help fund celebrations of Illinois’ centennial. Supported by the state’s congressional delegation, the Commission successfully lobbied for the coin’s creation, and in June 1918, Congress approved its production. In August of that year, the Philadelphia Mint struck 100,000 coins, plus an additional 58 for testing purposes. Each coin was sold through Illinois banks and the Springfield Chamber of Commerce.
The 1918 Illinois Centennial Half Dollar was only the third U.S. commemorative half dollar at the time, following earlier commemorative coins honoring the completion of the Panama Canal and the William McKinley Memorial.

Design and Symbolism
Obverse (Front) Design
The obverse of the coin, designed by Chief Engraver George T. Morgan, shows a right-facing bust of Abraham Lincoln. This design was inspired by sculptor Andrew O’Connor’s life-size statue of Lincoln, located in front of the Illinois Capitol. Lincoln is depicted looking slightly downward, capturing his thoughtful nature. Surrounding Lincoln’s image are inscriptions reading “CENTENNIAL OF THE STATE OF ILLINOIS” along the top and “LIBERTY” to the right of his bowtie. The motto “IN GOD WE TRUST” and the date 1918 also appear on the obverse.
Reverse (Back) Design
The reverse, crafted by Assistant Engraver John Ray Sinnock, displays an eagle inspired by the Great Seal of Illinois. The eagle holds a federal shield in one talon and a rock in the other, symbolizing the state’s strength and unity. Above the eagle, a ribbon with the state motto, “STATE SOVEREIGNTY, NATIONAL UNION,” and the phrase “E PLURIBUS UNUM” emphasize Illinois’ role in the United States. The reverse is framed by the inscriptions “UNITED STATES OF AMERICA” and “HALF DOLLAR.”
