The State Quarter Program, launched in 1999 and completed in 2008, remains one of the most popular coin series in American history. Each quarter represented one of the fifty states, with unique designs that captured local heritage and culture. While most of these coins are common and worth only face value, certain rare varieties, minting errors, and low-mintage issues have become treasures worth hundreds, thousands, and even more. In 2026, collectors continue to pay strong premiums for these rarities, making the State Quarter series a fascinating area of modern numismatics.
The Story of the State Quarter Program
The program was introduced by the U.S. Mint to encourage coin collecting and celebrate state pride. Each year, five new designs were released, eventually covering all fifty states. The quarters were struck in both copper-nickel clad and 90% silver versions for collectors. With billions produced, most are easy to find, but certain varieties stand out as rare and valuable.
