Most people think of state quarters as pocket change, but a few rare ones can actually be worth tens of thousands—sometimes even over $100,000. These high-value coins are often the result of minting errors, low production numbers, or special variations, and some may still be circulating undetected today.
If you’ve got a jar full of quarters, you might want to take a closer look—these 6 rare state quarters could be worth more than $100,000 each.
1. 1999-P Delaware State Quarter (Spitting Horse Error)
Estimated Value: Up to $5,000+ in high grade
The “Spitting Horse” quarter is one of the most famous error coins from the state series. On some 1999-P Delaware quarters, a die crack makes it look like Caesar Rodney’s horse is spitting.
Why It’s Valuable:
While common examples might be worth $10–$25, rare high-grade or dramatic versions of this error can sell for thousands. Mint State (MS67+) versions are especially sought after.
2. 2004-D Wisconsin State Quarter (Extra Leaf Error)
Estimated Value: $50,000–$125,000
This coin has two famous varieties: the “Extra Leaf Low” and “Extra Leaf High”, where an extra leaf appears on the corn stalk. These errors were discovered in 2004 and created a frenzy among collectors.
Why It’s Valuable:
Both varieties are rare, and coins in excellent condition have fetched upwards of $100,000. Even worn examples can sell for several thousand dollars.
3. 2001-P Vermont State Quarter (Double Die Obverse)
Estimated Value: $2,000–$10,000
Some Vermont quarters struck in Philadelphia show noticeable doubling on the obverse, especially around the words “IN GOD WE TRUST” and “LIBERTY.”
Why It’s Valuable:
This doubled die error is rare and highly desirable. The sharper and clearer the doubling, the higher the value—especially in mint condition.
4. 2000-P South Carolina Quarter (Off-Center Strike)
Estimated Value: $1,000–$10,000+
Coins that are struck off-center can range in value depending on how far off the design is. Some South Carolina quarters were minted this way, and complete dates and readable features make them more valuable.
Why It’s Valuable:
Off-center strike errors from the state quarter series are rare. Well-centered error coins with minimal wear can reach four or even five figures at auction.
5. 1999 Georgia Quarter (Experimental Planchet)
Estimated Value: $50,000–$100,000+
This coin was accidentally struck on a different metal planchet used for early tests of the Sacagawea dollar. Instead of the normal copper-nickel finish, it has a golden tone.
Why It’s Valuable:
Only a handful exist. These are considered test coins that somehow made it into public circulation. Their rarity and mystery have pushed their value well over $50,000.
6. 2005 Minnesota Quarter (Multiple Extra Trees Error)
Estimated Value: $1,000–$15,000+
This quirky error involves doubling in the tree line, making it look like extra trees were added near the Minnesota state outline.
Why It’s Valuable:
Multiple versions of this doubling exist, but strong examples in mint state can command impressive prices from collectors—especially for those graded MS65 or higher.
What Makes These Quarters So Valuable?
- Minting Errors: Double dies, off-center strikes, and die cracks.
- Low Mintage or Experimental Strikes: Some coins were produced in very small numbers or on unusual materials.
- High Condition: Coins graded MS66 or higher are much more valuable.
- Collector Demand: Unique designs and errors are highly sought after in the numismatic community.
How to Check Your Quarters for Value
- Look at the date and mint mark
(Ex: “P” for Philadelphia, “D” for Denver) - Inspect for unusual features
Doubling, cracks, off-center images, or extra elements - Use a magnifying glass
Some errors are hard to spot with the naked eye - Weigh the coin
If it weighs differently than standard quarters (~5.67 grams), it may be a planchet error - Check with a coin dealer or grading service
Companies like PCGS or NGC can authenticate and grade your coin
