You're digging through a jar of old change. Most of it is junk. Zinc pennies, worn-down Dimes, and a endless sea of standard Washington quarters. But then you see it. The 2004 Wisconsin state quarter. You’ve heard the rumors. You remember that one news story from years ago about a "extra leaf" that turned a twenty-five-cent coin into a payday.
It's real.
The 2004 Wisconsin state quarter with extra leaf value isn't just some internet myth cooked up by bored numismatists. It is one of the most famous modern "error" coins in American history. People actually found these in grocery store checkout lines in Tucson, Arizona, back in late 2004. Since then, it’s become a legitimate hunt.
What’s the Big Deal With the Leaf?
Basically, the Wisconsin quarter features a cow, a round of cheese, and an ear of corn. It’s a very "Wisconsin" design. But on a small number of coins minted in Denver (look for that little "D" mint mark), an extra mark appeared on the left side of the corn stalk.
It looks like a leaf. It shouldn't be there.
There are two distinct versions that collectors go crazy for. You’ve got the High Leaf and the Low Leaf. The High Leaf version has a small, curved line that starts near the top of the ear of corn and arcs toward the cheese. The Low Leaf is a bit more dramatic; it’s a lower, thicker arc that almost touches the cheese wheel.

Honestly, nobody knows for sure. The official line from the U.S. Mint back in the day was that it was a "die defect." But if you talk to old-school coin collectors—the guys who spend eight hours a day under a magnifying lamp—they'll tell you it looks a little too deliberate to be a simple accident. Some people think a mint employee was bored or disgruntled and used a tool to "engrave" these extra marks onto the dies. Whether it was sabotage or a fluke, the result was a massive spike in value.
The 2004 Wisconsin State Quarter With Extra Leaf Value: What It’s Actually Worth
Let's talk money because that’s why you’re here.
Values fluctuate. The coin market is basically the stock market but with more metal. Back in 2005, when the hype was at its peak, people were paying crazy prices—sometimes over $1,500 for a set. Things have calmed down since then, but these coins are still worth way more than twenty-five cents.
A raw, circulated Low Leaf might fetch you $50 or $60 if it's in decent shape. If it's a High Leaf, you’re looking at maybe $70 to $100 for a circulated copy. But the real money is in "Uncirculated" or "Mint State" coins.
If you have a 2004-D Wisconsin quarter that looks like it just popped out of a fresh roll, and it has the Low Leaf, you’re looking at $150 to $300. The High Leaf is rarer. In high grades like MS-66 or MS-67 (professional grading terms for "almost perfect"), these can sell for $500 to over $1,000. In fact, a High Leaf graded MS-67 by PCGS (Professional Coin Grading Service) once sold for over $6,000 at auction.
That’s a lot of cheese for a coin with a cow on it.

How to Tell if You Have a Winner
Don't just squint at it. Grab a magnifying glass or use the macro setting on your smartphone camera. You’re looking at the left side of the corn.
- Check the Mint Mark: It has to be a "D" for Denver. Philadelphia ("P") quarters don't have this error.
- The High Leaf: Look for a thin, leaf-shaped line that starts high on the corn stalk and curves toward the corn husk. It sits well above the cheese wheel.
- The Low Leaf: This one is much lower. The "leaf" starts near the bottom of the corn and arcs downward, almost touching the top of the cheese.
If you see a faint scratch or a tiny dent that doesn't quite look like a leaf, it’s probably just "Post-Mint Damage" (PMD). Coins lead rough lives. They get dropped, stepped on, and rattled around in vending machines. A real Extra Leaf error is raised—it’s "incuse" or embossed—meaning it was part of the strike itself, not a scratch added later.
Why the Tucson Connection Matters
Here is a weird bit of history. Almost all of these coins were originally discovered in the Tucson, Arizona area.
Back in December 2004, a collector named Bob Ford noticed the variety while looking through $1,000 worth of quarters he got from a bank. It’s estimated that only about 2,000 to 5,000 of each variety (High and Low) exist. Compare that to the nearly 500 million Wisconsin quarters minted in total.
The odds of finding one in your pocket today? Slim. But not zero.
Because these were released into general circulation, they traveled. They went to Vegas. They went to New York. They went to Florida. They are still out there, hidden in jars and sofa cushions, waiting for someone who knows what to look for.

Is It Worth Getting Graded?
This is where people lose money.
Professional grading costs money—usually $30 to $50 per coin plus shipping and insurance. If your quarter is scratched up and looks like it’s been through a war, don't send it to PCGS or NGC. A "Grade 10" circulated coin isn't worth the fee.
However, if you find one that is shiny, lustrous, and has zero scratches on the cow’s face or the cheese, get it graded. A "slabbed" coin (one sealed in a plastic holder by experts) is much easier to sell on eBay or at a local coin shop because the buyer knows it’s authentic. There are fakes out there. People try to scratch "leaves" onto regular quarters all the time.
Actionable Steps for Your Search
Stop spending your quarters without looking at the back. It sounds paranoid, but it takes two seconds.
First, separate any 2004 Denver quarters from your change. Set them aside. Once you have a few, get a bright desk lamp and a 10x jeweler’s loupe. Look specifically at the area between the corn and the cheese. If you see that extra line, compare it to high-resolution photos online from reputable sites like PCGS CoinFacts to confirm which leaf you have.
If it looks legit, take it to a local coin shop—not a pawn shop. Pawn shops will lowball you. A real coin dealer will be excited to see it and might offer you a fair price on the spot, or at least tell you if it’s worth the cost of professional certification.
Keep an eye out for the "Spitting Horse" Delaware quarter or the "Speared Bison" nickel too while you're at it. The world of modern errors is huge, but the 2004 Wisconsin state quarter with extra leaf value remains the undisputed king of the 50 State Quarters program. It changed how people looked at their pocket change, proving that sometimes, a mistake at the factory is the best thing that can happen to your wallet.
Check your jars. Check your car’s cup holder. You might be sitting on a few hundred dollars and not even know it.
