The reverse design of the South Dakota Quarter features Mount Rushmore. The inscriptions include the State name, Statehood date, mintage date, and “E Pluribus Unum.” The coin’s reverse was designed and engraved by John Mercanti.
Mount Rushmore National Monument features likenesses of four American Presidents: George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln. The reverse design also includes the Chinese ring necked pheasant, which is the state bird of South Dakota. The entire design is bordered by wheat ears.
The South Dakota Quarter Advisory Committee accepted and reviewed ideas from the state’s citizens. Five possible design concepts were selected and forwarded to the United States Mint. The governor selected the Mount Rushmore and Pheasant design, and the US Treasury Department provided final approval. Other designs considered included a three-quarter view of Mount Rushmore, the America Bison, and the Chinese Ring-necked Pheasant.
