The U.S. Mint State Quarters program, which started from 1999 to 2008, thrilled collectors and average citizens alike with special designs featuring each of the 50 states. Though millions of coins were minted, a select group has turned remarkably rare and, as a result, unusually expensive.
To date, six individual state quarters have been discovered being circulated in the marketplace with a total estimated worth of $267 million to collectors. These coins, because of errors in minting, limited manufacturing runs, or special qualities, are now rare treasures.
So here is what you need to know about these rare quarters and how you can possibly identify one in your coin purse.
1. 2004-D Wisconsin State Quarter (Extra Leaf Error – High and Low)
Possibly the most highly debated error coins of U.S. numismatics, the 2004-D Wisconsin quarter bears a corn stalk design with one or more observable “extra leaves” on several coins.

The extra leaves that point high or low resulted from an anomaly in the minting that rapidly made such coins collector’s gold.
- How it’s rare: A few thousand were made with the extra leaf error.
- Value: Depending on the condition, each coin can retail for $2,000 to more than $6,000.
2. 1999 Delaware State Quarter (Spitting Horse Error)
The Delaware quarter was the first to debut in the state series and depicts Caesar Rodney on horseback. Some versions have a die crack on the horse’s mouth, creating the illusion that the horse “spits.”
- Why it’s scarce: It’s a die crack mistake, and though widespread, mint condition ones are in great demand.
- Value: Varies between $10 and $250, with uncirculated coins selling even higher.
3. 2005 Minnesota Quarter (Extra Tree Error)
The Minnesota state quarter is a stunning natural lakeside landscape, but some versions include one or more “extra trees” that weren’t in the initial design. This is the result of a die clash or doubling during the coining process.
- Why it’s rare: Numerous varieties of this error have been discovered.
- Value: Based on severity and condition, these can fetch $50 to $600.
4. 2001-P Vermont State Quarter (Snow on Trees Error)
There are some Vermont quarters that have “snow” on trees, thanks to die polishing missteps. Not strictly a mint error, per se, but a clear design variation that has garnered collector attention.
- Why it’s rare: It’s an apparent aberration from normal design and rare in circulation.
- Value: Generally worth between $30 and $500, based on quality.
5. 1999 Georgia Quarter (Off-Center Strike)
The Georgia state quarter sometimes appears with a noticeable off-center strike, meaning the entire design is slightly shifted, leaving a blank crescent of metal on one side.
- Why it’s rare: Off-center strikes are difficult to control and rarely leave the mint.
- Value: Well-centered examples can be worth $100 to $1,000, depending on severity.
6. 2002-P Indiana Quarter (Missing Mint Mark)
The 2002 Indiana quarter with a race car has a variant where the “P” mint mark is omitted because of a filled die minting error.
- Why it’s rare: Mint marks are normally found on all coins minted today; absent ones are considered striking anomalies.
- Value: These quarters can be worth $500 to more than $1,500, depending on condition.
Why Are These Quarters Still in Circulation?
You might wonder why these valuable coins are still floating around. The reason is awareness or rather, the absence of it. Most people have no idea that these variants are even out there. Being quarter money that is seen on a daily basis, the coins do not receive a thorough examination before being spent.

That leaves some of these high-value coins potentially still circulating through vending machines, store registers, or tip jars.
How to Identify These Rare Quarters
Here are some tips for identifying valuable state quarters:
- Employ a magnifying glass to inspect finer details.
- Scan for design irregularities such as additional objects, cracks, or distortions.
- Check the mint mark, and record any that are missing or irregularly shaped.
- Compare your quarter with online guides or recognized error examples.
- Watch for condition mint state or uncirculated quarters sell for more money.

- Professional coin grading services such as PCGS or NGC
