One of the most popular and successful coin initiatives in American history is the Statehood Quarter Program. Coin collecting gained popularity globally as a result. The U.S. Mint introduced it in 1999 and produced unique quarters for every state in the union between 1999 and 2008. These coins featured George Washington on the obverse with a design on the reverse that celebrated each state’s distinct tradition, culture, or emblem.
About 400 million quarters were sent to each state, out of an estimated 34.3 billion total. But not every state quarter is made equal. Some are highly desirable to collectors now because they are rare because of reduced mintages or minting faults. Let’s explore the top 13 state quarters in terms of value and discover why they are worth much more than 25 cents.

1. 1999-P Experimental Delaware State Quarter
This rare quarter is part of a unique experiment conducted by the U.S. Mint in 1999. The Mint tested new alloys for the upcoming Sacagawea dollar by using them to strike some state quarters. Only a few states were involved—Delaware, Connecticut, Pennsylvania, New Jersey, and Georgia.
The 1999-P Delaware quarter struck in this experimental alloy is one of the rarest. With its shiny, gold-tinted appearance and slightly different weight and texture, it stands out. Only a handful were made, and even fewer survived. One of these coins graded MS66 sold for $4,888 at auction. If you find one of these in your collection, you might be sitting on a small fortune.
2. 2003-D Maine State Quarter
Released in June 2003, the Maine quarter depicts the Pemaquid Point Lighthouse and a schooner at sea. Most circulated examples are common, but high-grade coins—especially those graded MS68 or higher—are very rare.
In fact, a 2003-D Maine quarter graded MS68 fetched $2,300 at a 2017 auction. If you think you have a pristine Maine quarter, it’s worth getting it professionally graded. This is one of those coins where condition really makes a huge difference.
3. 2000-P South Carolina State Quarter
The South Carolina quarter, released in 2000, features the state outline, a star where the capital is, and three major state symbols. While most of these are common, mint state coins in perfect condition are very hard to find.
Only a few have been certified at the MS69 level, and one of these sold for an incredible $8,000 in 2018. It’s a great example of how modern coins can become surprisingly valuable due to condition and scarcity.
4. 2004-D Wisconsin State Quarter: Extra Leaf Low
Among the most famous error coins from the state quarter series, the 2004-D Wisconsin quarter features an extra leaf on the left side of the corn stalk on the coin’s reverse.
There are two varieties—Extra Leaf Low and Extra Leaf High—and both are valuable, especially in high grades. These were not intended by the Mint and are believed to have been die errors. One Extra Leaf Low coin in MS67 condition sold for $6,000 at auction.
5. 1999-P Connecticut State Quarter (Experimental Planchet)
Like the Delaware quarter, the Connecticut quarter from 1999 was also part of the experimental alloy testing. It stands out with a golden color and a smooth edge (compared to the standard reeded one). These planchet errors make the coin heavier and more desirable to collectors.
An example graded MS69 sold in 2018 for a jaw-dropping $10,500. If you notice a Connecticut quarter that looks or feels a little different, it might be worth a second look.
6. 1999-P Delaware State Quarter
As the first coin in the series, the Delaware quarter holds special historical value. It features Caesar Rodney’s famous horseback ride and is widely collected. Many were saved in uncirculated rolls and sets when it was first released, but high-grade specimens are still rare.
An MS66 example once sold for $4,888. While not as valuable as some error quarters, it’s still a solid coin to have in your collection.
7. 1999-P Pennsylvania State Quarter (Experimental Planchet)
Another coin from the Sacagawea alloy experiments, the 1999-P Pennsylvania quarter is incredibly rare and valuable in the right condition. If you find one with the golden tone and no reeded edge, it’s worth serious money.
One graded MS67 sold for $2,520, making it one of the most valuable coins from that year.
8. 2006-D North Dakota State Quarter
The North Dakota quarter is easy to find in your pocket change. However, those in mint state—especially MS68 or higher—are a different story. A coin in this grade sold for $3,760 at auction.
It’s a reminder that even modern coins can fetch big bucks if they are in top condition. Keep your eyes open for coins that look fresh out of the mint.
9. 2004-P Texas State Quarter (Grease Strike-Through Error)
Grease strike-through errors happen when grease fills the die, causing parts of the design to be missing or faint. One such Texas quarter struck with this error sold for $10,000 at auction.
Even standard MS69 Texas quarters (without error) can be worth over $3,000. This makes Texas one of the more profitable states for collectors with high-grade coins.
10. 2008-D New Mexico State Quarter
The 2008-D New Mexico quarter is one of the tougher coins to find in high grade. While over 244 million were made, few survived in mint state due to how they were handled.
An MS62 example alone fetched $2,500, and higher grades can go for more. This quarter is an excellent example of how mintage numbers don’t always equal value—it’s the quality that counts.
11. 1999-D Connecticut State Quarter
As the last state quarter of the 20th century, the Connecticut quarter is memorable for its Charter Oak design. Though over 657 million were minted, very few have remained in high-grade condition.
One example graded MS68 sold for $2,300 in 2018, showing how even heavily circulated coins can be valuable if preserved well.
12. 2006-P Nebraska State Quarter
With its unique design featuring a covered wagon and Chimney Rock, the Nebraska quarter is popular among collectors. Like others, circulated versions are common, but top-grade ones are rare.
An MS68 coin sold for $2,350 in 2017. Again, grading makes all the difference when it comes to value.
13. 1999-P Georgia State Quarter (Double Struck, Deep Die Cap Error)
This fascinating error coin was double struck after getting stuck in the die, leading to a mushy and blurred reverse design.
The 1999-P Georgia quarter with this rare minting error sold for a stunning $4,200 in 2022. It’s one of the rarest and most desirable errors in the state quarter collection.
Conclusion
State quarters are a fun and affordable way to start coin collecting, but they can also be a goldmine—literally. Most of them are worth just face value, but those with mint errors or in near-perfect condition can sell for thousands of dollars.
If you want to focus your collection on valuable coins, aim for high-grade quarters or those with known minting errors. Look especially for coins from Wisconsin, Maine, South Carolina, Connecticut, and Georgia, as these are among the rarest and most valuable.
