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 central image of the Arizona quarter is the magnificent Grand Canyon, which is one of the seven natural wonders of the world. It covers more than 1.2 million acres in northwestern Arizona, and joined the National Park system in 1919. Sculpted by the Colorado River, it is up to 6,000 feet deep and 18 miles wide. The "Saguaro Cactus", is shown in the design. The Saguaro Blossom is the state flower of Arizona. Also, and finally, the last component shown is a banner featuring the state nickname, "Grand Canyon State."

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