The 2006 issues of the 50 State Commemorative Quarter program feature inspired renditions of western geography and wildlife on the Nevada, Nebraska, Colorado and North Dakota quarters - as well as the revered Mount Rushmore memorial on the South Dakota quarter. These splendid western motifs include mustangs, buffalo, covered wagons and the Rocky Mountains - brought vividly to full living color by Littleton's artists! These eye-catching coins will be exciting additions to your 50 State Commemorative Quarter Collection.
