Introduction
State quarters, introduced by the United States Mint in 1999, have become a beloved part of American numismatics. While these coins are common, some contain rare errors that can make them incredibly valuable. This comprehensive guide explores the fascinating world of state quarter errors, highlighting sought-after mistakes that could be hiding in your spare change.
Understanding Coin Errors
Before delving into specific state quarter errors, it's crucial to understand what makes a coin error valuable:
- Rarity: Fewer examples typically result in higher value.
- Visibility: Easily noticeable errors often command higher premiums.
- Historical significance: Some errors gain fame due to unique circumstances.
- Condition: Better-preserved specimens are worth more.
Notable State Quarter Errors
1. The 2004-D Wisconsin "Extra Leaf" Quarter
One of the most famous state quarter errors occurred on the 2004 Wisconsin quarter minted in Denver. Two distinct varieties exist:
- Extra Leaf Low: An additional leaf appears low on the ear of corn.
- Extra Leaf High: The extra leaf is positioned higher on the corn.
These errors have sold for thousands of dollars, with the "Extra Leaf Low" variety fetching up to $6,000 in top grades. The cause of this error remains a mystery, adding to its allure among collectors.
2. The 2005-P Minnesota "Extra Tree" Quarter
Some Minnesota quarters from the Philadelphia mint feature what appears to be an extra tree in the state's outline. This error is subtle but can be quite valuable, with prices ranging from $100 to over $500 depending on condition.
3. The 2005-D Kansas "In God We Rust" Quarter
A clogged die resulted in the word "Trust" appearing as "Rust" on some Kansas quarters. This humorous error has captured the imagination of collectors and can sell for $50 to $100 or more.
4. The 2009 District of Columbia Quarter with a Double Die Reverse
Some D.C. quarters from 2009 show doubling on the reverse, particularly noticeable in the lettering. High-grade examples of this error have sold for over $3,000 at auction.
5. The 1999-P Delaware Spitting Horse Quarter
On some Delaware quarters, a die break near the horse's mouth gives the appearance that the horse is spitting. While not as valuable as some other errors, these quarters still command a premium and are popular among collectors.

Spotting State Quarter Errors
To find valuable state quarter errors, pay attention to these areas:
- Text: Look for doubling, missing letters, or oddly shaped characters.
- Images: Check for extra elements, missing details, or misaligned designs.
- Edges: Inspect for unusual shapes, cuts, or missing reeds.

Tools for Error Hunters
If you're serious about finding state quarter errors, consider investing in:
- A good magnifying glass or loupe (10x to 20x magnification)
- A digital scale accurate to 0.1 grams
- Reference books such as "Strike It Rich with Pocket Change" by Ken Potter and Brian Allen
- A smartphone with a high-quality camera for documentation
The Rarest of the Rare: Mules and Wrong Planchet Errors
While extremely rare, some of the most valuable state quarter errors are:
- Mules: Quarters struck with mismatched dies, such as a state quarter obverse paired with a Sacagawea dollar reverse.
- Wrong planchet errors: State quarters struck on planchets intended for other denominations.
These errors can be worth tens of thousands of dollars or more. For example, a state quarter struck on a Sacagawea dollar planchet sold for over $100,000 at auction in 2016.
Preserving Your Finds
If you believe you've found a valuable state quarter error:
- Handle the coin by its edges only
- Store it in a non-PVC holder
- Avoid cleaning the coin
- Consider having it professionally graded and authenticated by PCGS or NGC
The Market for State Quarter Errors
The market for state quarter errors remains strong, driven by:
- Nostalgia for the State Quarters Program
- The accessibility of the series to collectors of all levels
- The thrill of potentially finding valuable errors in circulation
According to recent market data, the overall value of state quarter errors has increased by approximately 15% over the past five years, outpacing inflation and demonstrating sustained collector interest.
Beyond State Quarters: Other Modern Error Coins
While state quarters offer many error collecting opportunities, don't overlook other modern series:
- America the Beautiful Quarters
- Presidential Dollars
- Native American Dollars
- American Innovation Dollars
These series have produced their own interesting errors. For example, the 2007 Washington Presidential Dollar with a missing edge lettering error has sold for over $5,000 in top grades.
The Future of Error Coin Collecting
As minting technology improves, major errors become less common. However, this scarcity may increase the value of known errors over time. The U.S. Mint's quality control measures have reduced error rates from approximately 1 in 10,000 coins in the early 2000s to less than 1 in 250,000 today.
Additionally, the rise of digital documentation and online communities has made it easier for collectors to share information and authenticate finds. Websites like CoinWorld.com and forums on CoinTalk.com have become valuable resources for error coin enthusiasts.
