The reverse of the Arizona quarter features an image of the Grand Canyon with a Saguaro cactus in the foreground. A banner reading "Grand Canyon State" separates the two images to signify that the Saguaro cactus does not grow in the Grand Canyon. Launched in 1999 the United States Mint s 50 State Quarters Program was a 10-year initiative that honored each of the nation s states in the order that they ratified the Constitution or were admitted into the Union. Each quarter was produced for about 10 weeks and will never be produced again. State designs are displayed on the reverse (tails) of the quarters while the obverse design displays the familiar image of George Washington. But to accommodate state designs on the reverse the words United States of America Quarter Dollar Liberty and In God We Trust all appear on the obverse.
