How Much Is A State Quarter Errors Worth?
Values for the state quarter error run from about face value (Ordinary state quarters) to $50–$200 (Major off-center strikes). Here is what separates the bottom of that range from the top — and how to find out where your coin lands.
History of the State Quarter Errors
The 50 State Quarters program put fifty different reverse designs into circulation and turned millions of Americans into change-checkers. Most state quarters are worth exactly 25 cents — but the program’s enormous production runs also produced some of the most famous modern errors.
The star is the 2004-D Wisconsin quarter with an "extra leaf" on the corn stalk, found in two versions (high leaf and low leaf) and traced to Denver die gouges. Alongside it collect off-center strikes, missing clad layers, and dramatic die breaks — all legitimate mint errors with real premiums.
The state quarter error was struck from 1999 to 2008 in copper-nickel clad. Production took place at Philadelphia and Denver.

When a coin fails any of these checks, treat it with suspicion. Modern counterfeits can be convincing at arm's length, but weight, dimensions and die details rarely lie.
- The Wisconsin extra leaf appears as a raised leaf pointing left from the corn husk — compare high-leaf and low-leaf reference photos.
- A missing clad layer shows a copper-colored face on one side with correct design detail.
- Ordinary strike doubling, dryer wear and vending damage are not errors and add no value.
