Lauched in 1999, the United States Mints' 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 to 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.

Missouri quarter missing.
