The State Quarters Program, initiated by the United States Mint in 1999 and concluded in 2008, introduced a fascinating chapter in American numismatics.
While most of these quarters are worth their face value, some have become highly sought-after collectibles due to errors, low mintages, or exceptional conditions.
As we delve into 2025, let’s explore ten of the most valuable state quarters that could be hiding in your pocket change or coin collection.
