This set if from the eighth year of honoring the states in the order they were admitted into the Union. The set features the following 2006 state quarter designs:
- Nevada’s "The Silver State"
- Nebraska’s "Chimney Rock"
- Colorado’s "Colorful Colorado"
- North Dakota’s "Badlands With Buffalo"
- South Dakota’s "Mount Rushmore And Pheasant"
This set is a shining embodiment of the United States Mint’s commitment to quality and excellence. United States proof coins are extraordinarily brilliant with sharp relief and a mirror-like background. Their frosted, sculpted foregrounds give them a special "cameo" effect, created by the proofing process. Proof blanks are specially treated, polished and cleaned to ensure high-quality strikes. The blanks are then fed into presses fitted with hand-polished dies and struck at least twice to ensure sharp, high relief. The coins are then packaged in presentation cases to showcase and maintain their exceptional finish.
