The U.S. State Quarters program, launched in 1999, was designed to celebrate each of the 50 states with unique designs on the reverse of the quarter. While most quarters are worth just 25 cents, rare errors and limited editions have skyrocketed in value, and some are now collectively valued at an astonishing $18 million.
Why State Quarters Can Be Worth Millions
Most quarters are mass-produced for circulation, but a few stand out due to:
-
Minting Errors: Misstrikes, double dies, or missing elements can make a quarter extremely rare.
-
Low Mintage: Some state quarters had fewer coins produced, increasing scarcity.
-
Proof or Special Mint Sets: Coins made for collectors in perfect condition often fetch high prices.
