State quarters remain one of the most popular and widely collected U.S. coin series. Launched from 1999 to 2008, these coins featured unique designs for all 50 states and quickly became a national collecting craze. Even today, their value continues to evolve—especially for rare errors, high-grade examples, and silver proofs. Over the past 11 years, shifting demand and new discoveries have reshaped the State quarter market, creating surprising price jumps for specific varieties.
This guide breaks down how values changed year by year and highlights which State quarters are now considered top performers.
