At first glance, the 2004-D Wisconsin State Quarter seems just like any other in the 50 State Quarters series. It proudly features a cow, a wheel of cheese, and an ear of corn—symbols of the state’s rich dairy heritage. But for sharp-eyed collectors, one version of this coin sparked a frenzy that no one saw coming. A tiny, accidental detail turned a common quarter into a hot-ticket collectible: the now-famous “Extra Leaf” error. These small variations, known as the “Extra Leaf High” and “Extra Leaf Low” varieties, were likely caused by accidental damage to the dies used in production. But their impact? Huge. What was once worth 25 cents suddenly became a coin worth hundreds—or even thousands—of dollars.
The Coin: 2004-D Wisconsin State Quarter (Extra Leaf Varieties)
In 2004, the U.S. Mint released the Wisconsin quarter as part of the ongoing 50 State Quarters Program. Coins were struck at various mints, including Denver (“D” mint mark). Partway through production, coin experts and collectors began noticing a small, unexplained feature on some of the Denver-minted coins: an extra leaf on the ear of corn.
Two main varieties of the error were identified:
- Extra Leaf High – A curved leaf extending higher up from the corn husk.
- Extra Leaf Low – A flatter leaf located lower, near the base of the corn.
These were not part of the original design by artist Alfred Maletsky. Experts believe the extra leaf was the result of damage or modification to the die, possibly from a tool slipping during maintenance or repair. What makes these coins even more intriguing is how rare and specific the error is: it appears only on Denver-minted quarters from a specific die run, meaning only a limited number made it into circulation.
How Valuable Is It?
Despite being a modern coin, the Extra Leaf varieties skyrocketed in value shortly after discovery. Early finds were selling for $300 to $1,000, and prices have remained strong ever since. Today, depending on condition and type:
- Extra Leaf Low coins typically range from $150 to $500.
- Extra Leaf High coins, which are slightly rarer, can sell for $300 to $1,000+ in uncirculated grades.
Graded and certified examples—especially those in Mint State (MS) condition by PCGS or NGC—carry even more value. It’s a perfect reminder that even everyday pocket change can hold incredible surprises.
The 2004-D Wisconsin Extra Leaf Quarter shows us that you don’t have to go digging through ancient collections to find treasure—sometimes, it’s hiding in your own spare change. As one of the most exciting modern error coins in circulation, it proves how small mistakes can make a huge difference in numismatics. Whether you’re a seasoned collector or a beginner checking your quarters, keep an eye out for that extra leaf—it might just turn 25 cents into hundreds of dollars.
