In December 1997, America's most adventurous coin program became a reality when President Clinton signed legislation authorizing the U.S. Mint to issue the innovative 50 State Quarters collection. Starting in January 1999, each of the 50 states in the Union will be honored on a unique Quarter Dollar commemorative coin. Five states were featured each year, based on the order in which they ratified the Constitution or became states. On the front, otherwise known as the obverse, the mintmarks can be found to the right of George Washington's portrait. The small "S" indicates San Francisco Mint.

The final design for this Oklahoma quarter is the State Bird, the "Scissortail Flycatcher", in flight together with the state wildflower, Indian Blanket. The Indian Blanket represents represents the state's Native American heritage.

Each coin is encapsulated - please keep the coins in their protective coin holder to maintain their condition.
