Most State Quarters (1999–2008) are worth just 25 cents—but a small group of rare errors and high-grade examples have become surprisingly valuable. Some have sold for hundreds or even thousands of dollars, making them coins you definitely should not spend if you find one.
This guide explains which state quarters are valuable, why they’re worth money, and how to identify them before they disappear back into circulation.
Why Some State Quarters Are Valuable
State quarters gain value due to:
- Major mint errors
- Limited production mistakes
- High-grade condition (MS67+)
- Strong collector demand
- Registry set competition
Age alone does not determine value—rarity does.
