Product Description
The enormously popular U.S. 50 State quarter series began in 1999. These finest-quality proofs are the scarcest and most beautiful form of the innovative quarters. This set contains the five 2006 quarters with unique designs honoring the history and traditions of Nevada, Nebraska, Colorado, North Dakota and South Dakota. Each copper-nickel quarter proof was struck by the San Francisco Mint with deep-etched frosted engravings contrasting with mirror backgrounds.
