The 50 State Quarters program, launched by the U.S. Mint between 1999 and 2008, was designed to celebrate the heritage of each state.

Why Are State Quarter Errors So Valuable?
Several factors contribute to the high value of error quarters:
- Scarcity: Minting errors are rare, making these coins highly desirable to collectors.
- Unique Features: Distinctive visual anomalies such as doubling, missing layers, or design shifts make them stand out.
- Condition: Higher-grade, well-preserved error coins tend to fetch premium prices.
Key State Quarter Errors by Type
