Imagine discovering a regular-looking quarter in your pocket—only to find out it’s worth thousands of dollars. While most state quarters are worth face value, a few rare ones from the 50 State Quarters Program (1999–2008) have become incredibly valuable due to minting errors and unusual variations.
These rare quarters are still circulating and can be found in everyday change, coin jars, and even vending machines. Here’s a breakdown of five valuable state quarters that collectors are hunting for—and that could be worth more than $5,000 each.
1. 1999 Georgia State Quarter – Wavy Flag Error
What Makes It Special?
Some 1999 Georgia quarters feature a unique minting error where the flag on the reverse side appears wavy instead of flat.
Estimated Value:
Up to $7,000 in uncirculated condition.
Why Collectors Want It:
This error slipped through quality control, making it extremely rare. Its unusual appearance and limited quantity make it highly desirable among numismatists.
How to Identify:
Inspect the flag closely—if it looks wavy or distorted, you could be holding a hidden gem.
2. 2004 Wisconsin State Quarter – Extra Leaf Error
What Makes It Special?
Two rare variations of this coin include an extra leaf near the corn stalk—either pointing “high” or “low.”
Estimated Value:
Between $6,000 and $10,000, depending on condition and variety.
Why Collectors Want It:
This die flaw occurred during the minting process and created one of the most famous error coins of the state quarter series.
How to Identify:
Look at the corn stalk on the reverse side. If you notice an unusual extra leaf, get the coin professionally evaluated.
3. 2005 Kansas State Quarter – “In God We Rust” Error
What Makes It Special?
A striking minting error caused the motto “In God We Trust” to appear as “In God We Rust.”
Estimated Value:
Up to $5,000 in mint state.
Why Collectors Want It:
This humorous and rare printing error is a favorite in the coin community. The missing “T” was due to grease on the die.
How to Identify:
Check the front (obverse) of the coin. If the “T” in “Trust” is missing or faint, you may have found a rare collectible.
4. 1999 Delaware State Quarter – Spitting Horse Error
What Makes It Special?
This coin features a small die crack that makes it look like the horse is spitting.
Estimated Value:
More than $5,000 if in excellent condition.
Why Collectors Want It:
The error is subtle but unique. Because it’s both rare and quirky, collectors are willing to pay top dollar for it.
How to Identify:
Use a magnifying glass to check the horse’s mouth for a fine crack extending outward—this is the spitting effect.
5. 2000 South Carolina State Quarter – Off-Center Strike
What Makes It Special?
This coin features a significant misalignment of the die, resulting in an off-center design.
Estimated Value:
Between $5,000 and $7,000, depending on how far the design is shifted.
Why Collectors Want It:
Off-center strikes are visually obvious but extremely rare in the state quarter series. The more dramatic the misalignment, the more it’s worth.
How to Identify:
Look for a crooked or uncentered design—this is a telltale sign of a minting misstrike.

- Use a magnifier to inspect for die cracks, missing letters, or unusual details.
- Compare your coin to official U.S. Mint images or online coin databases.
