This set is from seventh year of honoring the states in the order they were admitted into the Union. The set features the following 2005 state quarter designs:
- California’s "John Muir and Yosemite Valley"
- Minnesota’s "Land of 10,000 Lakes"
- Oregon’s "Crater Lake"
- Kansas’s "Buffalo and Sunflower"
- West Virginia’s "New River Gorge"
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 a 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 a sharp, high relief. The coins are then packaged in presentation cases to showcase and maintain their exceptional finish.
