The State Quarters Program, launched in 1999, became one of the most popular coin series in U.S. history. Each quarter honored a different state with unique designs, sparking widespread interest among collectors and the general public. While most state quarters are common, certain rare varieties and mint errors have become highly valuable. In 2026, some of these coins can be sold for big money, making them treasures hidden in pocket change or coin collections.
Origins of the State Quarters Program
The program ran from 1999 to 2008, releasing five new designs each year. It was intended to celebrate the heritage and history of all 50 states while encouraging coin collecting among Americans. The initiative was a massive success, with millions of people saving quarters and building collections. However, not all quarters were struck equally, and some rare issues now stand out as valuable finds.
