Top 10 Most Valuable State Quarters That Are Worth BIG MONEY in 2025 – Check Your Change Now!
The 50 State Quarters Program, which ran from 1999 to 2008, sparked a nationwide passion for coin collecting. While the U.S. Mint produced billions of these quarters, a small number slipped through the process with dramatic errors, were struck on the wrong metal, or survived in pristine condition, making them worth a small fortune today. In the current 2025 coin market, some of these “ordinary” 25-cent pieces have auction records reaching into the thousands, and even over $10,000!
Forget face value—it’s the rare mistakes and impeccable condition that turn pocket change into a monumental treasure. Here is a countdown of the top ten most valuable State Quarters you should be hunting for in your spare change, coin rolls, and collections right now.
The Most Wanted Error Quarters
Error coins—those that are flawed due to a mistake in the minting process—are the true superstars of the State Quarter series. Their rarity and dramatic appearance drive prices sky-high.
1. 1999-P Connecticut Quarter – Experimental Planchet Error This quarter is one of the “Holy Grails” of the series. A tiny number of 1999-P Connecticut quarters were accidentally struck on experimental brass planchets originally intended for the Sacagawea dollar coin. These quarters are significantly heavier, appear with a noticeable golden sheen, and have a smooth edge instead of the standard reeded edge. One authenticated high-grade example (MS69) achieved a staggering $10,500 at auction, making it the most valuable known example of the State Quarter series.
2. 2004-D Wisconsin Quarter – “Extra Leaf” Error Found exclusively on the Denver Mint (D) quarters for Wisconsin (2004), this error features an extra leaf on the corn stalk on the coin’s reverse. The two main varieties are the “Extra Leaf Low,” where the leaf curves across the top of the cheese wheel, and the “Extra Leaf High,” where the leaf appears higher and more slender. The Extra Leaf Low variety has an auction record of over $6,000 for a high-grade example (MS67). Even circulated examples can trade for $50-$65.
3. 2004-P Texas Quarter – Grease Strike-Through Error When a die is clogged with excess grease, parts of the design may fail to transfer completely to the coin. In the case of the 2004-P Texas Quarter, this error is visible on the reverse. Examples of the Texas quarter with a significant grease strike-through have been known to fetch up to $10,000 for a nearly perfect MS69 grade.
4. 1999-P Delaware Quarter – “Spitting Horse” Error As the first quarter released in the program, the 1999-P Delaware quarter has a famous die break error that appears as a small, raised line of metal extending from the mouth of Caesar Rodney’s horse, making it look as though the horse is “spitting”. A top-graded specimen (MS66) holds an auction record of $4,888, though circulated examples of the “Spitting Horse” typically range from $10 to $15.
5. 1999-P Georgia Quarter – Deep Die Cap, Double Struck Error An extreme and rare error, the 1999-P Georgia quarter with a deep die cap and double struck is highly sought after by collectors. This error occurs when a coin is struck twice while stuck in the press, creating a distinct and dramatic impression. Such anomalies have commanded prices up to $4,200 at auction.
High-Grade Perfection & Doubled Dies
Beyond dramatic errors, simply finding a perfect or near-perfect example of certain state quarters can be extremely profitable, especially for low-population high-grade coins.
6. 2000-P South Carolina Quarter – MS69 Grade While millions were minted, finding the 2000-P South Carolina quarter in a near-perfect MS69 grade is exceptionally rare, with PCGS having graded fewer than a handful. Due to this scarcity in the highest condition, one MS69 example reached a value of $8,000.
7. 1999-P Pennsylvania Quarter – MS67 Grade The first State Quarter released, the 1999-P Pennsylvania quarter in flawless MS67 condition is a key high-grade coin. Its auction record stands at $10,200, set in 2006, highlighting the value collectors place on its exceptional preservation.
8. 2005-P Minnesota Quarter – Doubled Die Reverse (Extra Trees) This variety features clear doubling on the reverse, specifically appearing as “extra trees” in the image of the lake-lined forest. Depending on the severity of the doubling and the coin’s condition, these errors can be valued from a few dollars up to $150+ in top Mint State grades (MS65).
9. 2006-D North Dakota Quarter – MS68 Grade The North Dakota quarter, featuring two grazing bison, is another example where superior condition dictates its worth. A pristine MS68 graded coin from the Denver Mint (D) can be exceptionally rare and has sold for up to $3,760.
10. 2003-D Maine Quarter – MS68 Grade The Maine quarter, with its depiction of a schooner and Pemaquid Point Light, is highly sought after in top condition. A perfect MS68 example from the Denver Mint (D) has an auction record of over $2,300.
Always check your change carefully! The smallest flaw or the most brilliant luster could mean the difference between 25 cents and thousands of dollars.
