The U.S. State Quarters program, launched in 1999, became immensely popular as it celebrated each state with unique designs. While most state quarters are worth face value, certain rare varieties can fetch hundreds of dollars due to minting errors, unique features, or low mintage.
Here are some rare state quarters that are highly sought after and could be worth over $500 if you’re lucky enough to find one.
1999-P Delaware Quarter with Spitting Horse Error

2004-D Wisconsin Quarter with Extra Leaf Error
