State quarters are still turning up in pocket change, but some of them quietly sell for hundreds or even thousands of dollars. If you know which designs, dates and minting quirks to look for, you can spot valuable pieces hiding in jars, drawers and old collections. Here are 15 specific state quarters that collectors watch closely, and how their rare varieties can turn everyday change into serious money.

1) 2004 Wisconsin State Quarter

The 2004 Wisconsin state quarter is the modern benchmark for how valuable a circulating quarter can become. Reporting on this issue notes that certain Wisconsin coins with unusual leaf details on the corn stalk could be worth up to $6,000, especially in high grade, which is why collectors scrutinize every example they find. The design shows a cow, a wheel of cheese and an ear of corn, and it is that corn that holds the key to the big premiums.

Specialists point to extra leaf varieties on the reverse as the reason some of these coins sell for far more than face value. A detailed breakdown of these “Extra Leaf” pieces explains that the 2004-D Wisconsin quarter can bring strong prices, with documented sales in the hundreds and more for top-condition examples, which is how a coin worth 0.25 dollars in circulation can reach four figures. If you see an odd extra line on the corn leaf, the guidance from coverage of the $6K potential makes clear that you should have it checked by a professional grader.

2) 1999 Delaware State Quarter

The 1999 Delaware State Quarter Year was the first release in the program, and that alone gives it special status with collectors. A detailed state quarter guide notes that The Delaware design, featuring Caesar Rodney on horseback, has become a focus for error hunters because early production runs often reveal striking issues. Among the most watched are coins with unusual die breaks or doubled details that separate them from the 401,424,000 standard pieces listed for the Type identified as Delaware State Quarter Year with Mint Mark D, Face Value 0.25 USD and Total Produced 401,424,000 in one painted set listing.

Another specialist breakdown of valuable state quarters explains that state quarters with rare markings are worth big bucks, and it singles out early issues like Delaware as prime candidates for dramatic errors. When you combine that insight with video walk-throughs that show how a single 1999 Delaware coin with the right flaw sold for HUGE money, you can see why collectors still comb rolls from this year. For you, that means any Delaware quarter with odd doubling, missing letters or off-center strikes deserves a closer look.

3) 2000 Maryland State Quarter

The 2000 Maryland state quarter, featuring the Maryland Statehouse dome, is another design where rare markings can transform a common coin into a valuable find. Analysts who track the most valuable state quarters emphasize that unusual die varieties, such as strong doubling on the lettering or the dome, are what push prices far beyond face value. Because Maryland was an early release, large mintages increase the odds that some dramatic errors slipped into circulation.

Guidance on which state quarters to watch notes that collectors pay particular attention to crisp, uncirculated Maryland coins that also show clear anomalies. When a coin combines a popular design with a recognized error, it can join the list of pieces that sell for hundreds of dollars. For everyday holders, that means a Maryland quarter in exceptional condition, especially from a bank-wrapped roll or old mint set, is worth checking against online error photo guides before you spend it.

4) 2005 Minnesota State Quarter

The 2005 Minnesota state quarter is one of the best documented examples of how a subtle design variation can create big value. A detailed state quarter analysis explains that the 2005-P Minnesota issue has multiple doubled die varieties, where extra outlines of the trees appear near the lake scene. These doubled details are not damage, they are minting varieties, and they are exactly the kind of rare markings that specialists say are worth big bucks.

One in-depth guide to state quarters worth money notes that some Minnesota doubled dies have sold for strong premiums, especially in high grades, because they are both dramatic and relatively scarce. The same resource that highlights the Wisconsin Extra Leaf varieties also lists Minnesota doubled dies among the most desirable modern quarters, with certain examples bringing far more than the usual $0.25. If you live in a region where Minnesota quarters still circulate heavily, it is worth scanning the trees on every coin you handle for that extra set of branches.

5) 2004 Wisconsin State Quarter (High Leaf Variety)

The 2004 Wisconsin State Quarter (High Leaf Variety) deserves its own entry because it is a specific subtype of the Wisconsin design that collectors chase aggressively. A specialist breakdown of rare state quarters explains that the 2004-D Wisconsin “Extra Leaf” coins come in distinct High Leaf and Low Leaf versions, each showing an extra line near the corn husk. That same analysis notes that these Extra Leaf pieces can trade in the $50 to $65 range for circulated examples, with far higher prices for top-graded coins.

Because the High Leaf variety is visually striking, it is easier for non-experts to spot than many other errors. The guidance from the detailed state quarter value overview makes clear that this is one of the most important modern quarter varieties. For you, the implication is simple, any 2004-D Wisconsin quarter should be checked under good light, because even a moderately worn High Leaf example can be worth dozens of times its face value.

6) 2009 District of Columbia State Quarter

The 2009 District of Columbia state quarter, featuring Duke Ellington at a piano, is a later issue that some analysts see as a candidate for future gains. A forward-looking review of rare coins that will be worth big money in 10 years notes that modern commemorative quarters with low mintages and distinctive designs can become key pieces as collections mature. The District of Columbia coin fits that pattern, especially in high-grade examples and in any emerging error varieties.

Because 2009 marked the transition from the original state series to the District and territories, some collectors treat these issues as a bridge set that will gain attention over time. If demand for complete runs of the program continues to grow, top-quality District of Columbia quarters could see rising prices, particularly for certified coins. For you, that suggests setting aside sharp, uncirculated examples now, rather than assuming they will always be worth only face value.

7) 2008 Oklahoma State Quarter

The 2008 Oklahoma state quarter, with its scissortail flycatcher and wildflowers, is another design that forward-looking coin watchers flag as a potential climber. Analysts who evaluate which modern coins might be worth big money in a decade point out that later state quarters with strong regional symbolism can attract dedicated followings. Oklahoma’s detailed reverse, combined with relatively modest surviving populations in top grades, gives it that kind of long-term appeal.

While no single error dominates the Oklahoma issue yet, collectors already pay premiums for coins graded at the highest levels, especially from rolls that were saved at the time of release. As more casual holders spend or lose their quarters, pristine survivors become scarcer, which is exactly the dynamic highlighted in long-range coin value forecasts. If you find an Oklahoma quarter that looks freshly minted, it is worth protecting in a sleeve or album rather than dropping it back into circulation.

8) 1999 Pennsylvania State Quarter

The 1999 Pennsylvania state quarter, showing the Commonwealth statue and state outline, is a classic example of a coin you might already have at home that could be worth more than you think. A guide to things in your home that could be worth a lot of money reminds you that everyday items, including coins in jars and drawers, can carry unexpected value. Early state quarters like Pennsylvania are prime candidates, especially if they are uncirculated or show unusual minting flaws.

Collectors look for strong strikes, clean surfaces and any signs of doubling or die cracks on the Pennsylvania design. Because it was one of the first releases, many people saved rolls and mint sets, which means high-grade coins exist, but they are increasingly locked into collections. For you, that means checking old change containers, inherited coin folders and even childhood collections, since a pristine 1999 Pennsylvania quarter can bring more than face value when sold to a specialist buyer.

9) 2005 Kansas State Quarter

The 2005 Kansas state quarter, featuring a buffalo and sunflowers, has become famous among collectors for quirky errors that change the lettering on the coin. Some pieces show missing or partially struck letters in “IN GOD WE TRUST,” creating varieties that stand out immediately under casual inspection. These are exactly the kind of rare markings that state quarter experts say can turn a common coin into a valuable collectible.

Because Kansas quarters circulated widely, you still have a realistic chance of finding one of these oddities in pocket change or old rolls. Error-focused videos and guides often highlight Kansas as a must-check design, since the contrast between normal and flawed inscriptions is so obvious. For you, the takeaway is straightforward, any Kansas quarter with weak or missing letters, especially around “IN GOD WE TRUST,” should be set aside and compared to authenticated examples before you spend it.

10) 2006 Nevada State Quarter

The 2006 Nevada state quarter, with its trio of wild horses, connects directly to a broader pattern in coin collecting where older silver issues set the price ceiling for modern rarities. A detailed look at 5 coins from the 1960s that are worth a lot of money shows how pre-state quarter pieces, especially silver issues with low mintages or key dates, can sell for substantial sums. That history helps explain why collectors now pay close attention to modern quarters like Nevada that show promising scarcity or error potential.

While Nevada quarters are not silver, the same forces of condition, rarity and demand apply. High-grade examples, particularly from original rolls or mint sets, already bring premiums, and any confirmed errors could push certain coins into much higher price brackets, just as rare 1960s coins did over time. For you, that means treating sharp Nevada quarters with the same care you would give older collectible coins, since today’s modern issue can become tomorrow’s key date.

11) 2007 Wyoming State Quarter

The 2007 Wyoming state quarter, featuring a silhouetted bucking horse and rider, is another modern issue whose long-term value is easier to understand when you look at earlier coin trends. The same analysis of valuable 1960s coins that highlights how modest face-value pieces became worth serious money over decades also underscores the importance of design popularity and collector demand. Wyoming’s bold, minimalist design has already made it a standout within the state quarter series.

Collectors pay particular attention to Wyoming quarters with strong strikes and clean fields, because the large open areas on the reverse show marks easily. As with the Nevada issue, the combination of distinctive artwork and potential low survival rates in top grades positions Wyoming as a candidate for future price growth. For you, that suggests that any nearly flawless Wyoming quarter, especially one pulled from circulation early, could be worth submitting for grading if broader demand continues to build.

12) 2001 New York State Quarter

The 2001 New York state quarter, depicting the Statue of Liberty and state outline, is a favorite target for collectors who specialize in rare markings. A comprehensive guide to the most valuable state quarters explains that coins with unusual die varieties, doubled inscriptions or striking errors can command strong premiums. New York’s intricate design, with multiple inscriptions and fine lines, offers many opportunities for such varieties to appear.

Enthusiasts report interest in New York quarters that show doubling on “GATEWAY TO FREEDOM” or on the state outline, as well as coins with off-center strikes that leave part of the design missing. Because New York is one of the most recognizable and widely collected states, demand for dramatic errors is especially strong. For you, that means any New York quarter that looks slightly “off,” whether in lettering or layout, deserves a closer inspection and possibly a comparison with certified error images.

13) 2009 Puerto Rico State Quarter

The 2009 Puerto Rico state quarter, part of the District and territories series, combines a detailed fortress design with inscriptions that make it fertile ground for collectible errors. State quarter specialists who track rare markings note that later issues like Puerto Rico can develop valuable varieties, particularly when die wear or misalignment affects the fine details. Because the design includes both Spanish and English text, there are multiple areas where doubling or missing letters can occur.

Collectors also point out that territories quarters often had lower mintages than earlier state issues, which can magnify the impact of any significant error. As more people aim to complete full sets that include Puerto Rico, demand for both high-grade regular coins and dramatic varieties is likely to grow. For you, that means checking Puerto Rico quarters carefully, especially those that appear unusually sharp or, conversely, show odd distortions in the lettering or fortress walls.

14) 2007 Montana State Quarter

The 2007 Montana state quarter, featuring a large bison skull over a landscape, is frequently mentioned in discussions of modern coins that could be worth big money in the future. Analysts who look ahead at which issues might appreciate emphasize that distinctive designs with strong regional identity, like Montana’s, tend to attract dedicated collectors over time. When combined with relatively low surviving populations in top grades, that interest can translate into higher prices.

Some error hunters also watch Montana quarters for die breaks or unusual marks around the bison skull, which stand out clearly against the open background. While not every Montana coin will be a winner, the broader trend of rising interest in complete state quarter sets supports the idea that key designs will see growing premiums. For you, setting aside bright, uncirculated Montana quarters now is a low-cost way to participate in that potential upside.

15) 2000 Massachusetts State Quarter

The 2000 Massachusetts state quarter, showing a Minuteman statue and state outline, is a classic example of a coin you might already own that could be worth more than face value. Guides to common household items that might be valuable, including coins, stress that you should not overlook jars of change or old collections, because there could be overlooked state quarters among them. Early issues like Massachusetts are especially promising, since they were heavily used but also widely saved in the first years of the program.

Collectors look for Massachusetts quarters with sharp details on the Minuteman and clean fields, as well as any signs of doubling on the inscriptions. As with other early states, high-grade examples and confirmed errors can command premiums, particularly from buyers assembling top-tier sets. For you, that means checking any Massachusetts quarters you find in old rolls, inherited coin folders or forgotten containers, because a single high-quality piece can be worth far more than its small face value suggests.
