Have you ever wondered if the coins in your pocket are worth more than face value? Some state quarters circulating today are worth over $1,500! The 50 State Quarters Program (1999-2008) and the subsequent America the Beautiful Quarters series revolutionized coin collecting, creating a treasure trove of valuable finds. While most are worth just 25 cents, rare errors, special proof coins, and unique varieties can be incredibly valuable.
This comprehensive 2025 guide will show you exactly which state quarters are worth serious money. Plus, we'll reveal how the Coinly app can help you identify these valuable errors and varieties instantly with just a photo.
Why Are Some State Quarters So Valuable?

This historic program was designed to get Americans excited about coin collecting. Each state was honored with a unique design, creating a diverse and exciting series.

- Collecting Impact: It successfully brought millions of new people into the hobby, many of whom started by searching their pocket change.
America the Beautiful Quarters (2010-2021)
This series continued the tradition, featuring national parks and historic sites. Like the state quarters, these also have valuable error and proof versions.
