Description

The 2006 (D) Colorado State Quarter is a quarter minted at the Denver Mint, within the State Quarters 1999-2008 series. The Denver Mint struck 294,200,000 Colorado quarters dated 2006. The obverse features George Washington facing left, based on a 1786 bust by Jean-Antoine Houdon and the reverse displays unique designs representing each of the 50 U.S. states, released in the order the states ratified the Constitution or joined the Union. The reverse features a sweeping view of the Rocky Mountains with evergreen trees and a banner reading "Colorful Colorado." The state contains over 50 peaks above 14,000 feet. The 2006 quarters honored, in release order, Nevada, Nebraska, Colorado, North Dakota, and South Dakota. Denver's mint evolved from a frontier assay office into one of the nation's primary coin production facilities, opening in 1906. Estimated market value ranges from $0.25 to $3 depending on grade and condition. Struck in 75% copper, 25% nickel, weighing 5.67 grams, 24.3 mm in diameter, with a reeded edge. Cataloged as PCGS #39025.
