The 2006 State and Territorial Quarters are part of the United States Mint's 50 State Quarters Program, which began in 1999 and concluded in 2008. Each quarter features unique designs representing different states. In 2006, the quarters released were for Nevada, Nebraska, and Colorado, with themes reflecting their historical and cultural significance. Collectors often seek these quarters for their artistic designs, limited issuance, and the overall popularity of the program among numismatists.
