The approved design for the fifth and final 2011 National Park quarter, featuring Chickasaw National Recreation Area in Oklahoma, was announced on December 1, 2010 by the United States Mint.
The reverse of this 10th issue in the 2010-2021 National Park series depicts the Lincoln Bridge – the first and oldest constructed improvement to the natural setting of the recreation area. The limestone bridge was dedicated on February 12 (Lincoln’s birthday) in 1909, celebrating to the day the centennial of our 16th president’s birth. For over a century, the Lincoln Bridge has been a treasured landmark and revered piece of the park’s cultural landscape. The diverse foliage and wildlife of the recreation area are also represented by the design.
Inscriptions on the coin’s reverse include the site – CHICKASAW NATIONAL RECREATION AREA, its location – OKLAHOMA, year of issue – 2011, and motto E PLURIBUS UNUM. The obverse or “heads” side features a smaller restored version of the George Washington portrait introduced on quarters in 1932.
