The first commemorative quarter dollar released in 2008 honors Oklahoma, 46th state to join the Union (on November 16, 1907) and 46th quarter in the United States Mint's 50 State Quarters Program. Oklahoma's nickname is the "Sooner State."
The quarter's image features the scissor-tailed flycatcher, Oklahoma's state bird. Its tail, as long as its body, is spread open like scissors as it flies. The bird is soaring over the state wildflower, called "Indian blanket."
The Indian blanket (gaillardia) symbolizes Oklahoma's rich American Indian heritage, its native long grass prairies, and the prairies' abundant wildlife. Oklahoma was formed out of the Oklahoma Territory and the Indian Territory of the Five Civilized Tribes (Choctaw, Chickasaw, Creek, Seminole, and Cherokee). The state's name comes from the Choctaw words "okla" and "homma," meaning "red" and "people."
