5 Valuable State Quarters Worth Up to $6.7 Million Each – Still in Circulation

Could the Spare Change in Your Pocket Be Worth a Fortune? Discover 5 State Quarters That Might Make You a Millionaire! That dusty coin jar sitting in your kitchen could be hiding something extraordinary. While it may seem like ordinary spare change, certain coins from the U.S. Mint’s 50 State Quarters Program—released between 1999 and 2008—have surprised collectors and experts alike with their incredible value. Some of these unassuming coins have turned up at auctions and changed hands for massive sums, thanks to rare errors and limited mint runs.

Most state quarters in circulation today are only worth 25 cents, but a select few with rare errors or unique characteristics have become hot commodities. Some examples have even crossed the million-dollar mark, making them the stuff of legends. Below, you’ll discover five specific state quarters that could be hiding in your coin jar—and if you’re lucky enough to find one, it might just change your financial future.

1. 1999 Delaware Quarter

This coin kicked off the popular 50 State Quarters Program, paying tribute to Caesar Rodney’s legendary ride and Delaware’s historic role as the first state to ratify the U.S. Constitution. While the majority of these quarters are still only worth their face value, a rare few have become the focus of intense collector demand due to minting errors.

These prized errors can include double die strikes, off-center impressions, and other anomalies that occurred during production. One such coin reportedly sold for a staggering $6.7 million due to its rarity and condition. If you come across a 1999 Delaware Quarter that looks a little different—say, with blurred images or off-kilter printing—it could be a once-in-a-lifetime find.

2. 2004 Wisconsin Quarter – Extra Leaf Error

Celebrating Wisconsin’s agricultural roots, this coin showcases a cow, a wheel of cheese, and an ear of corn. But what truly sets this quarter apart is an unexpected detail: an extra leaf on the corn stalk. Depending on the variety, this extra leaf can either curve upward or downward—and that’s where the value lies.

These so-called “extra leaf” error coins are not common, and when found in uncirculated or pristine condition, they can command serious money. In fact, some examples have sold for over $1,500. It’s amazing how a small, unintended addition during the minting process can turn a typical quarter into a highly desirable collector’s item.

3. 2005 Minnesota Quarter – Double Die Error

The 2005 Minnesota Quarter highlights the state’s natural beauty, featuring a serene lake scene with a loon, the state bird. Yet what really makes this quarter special is a rare and valuable double die error, which creates a noticeable doubling in parts of the design—most visibly in the trees near the horizon.

This doubling effect wasn’t intentional, but collectors hunt for it because of its rarity. Depending on the visibility of the doubling and the coin’s condition, these error quarters have sold for anywhere between $100 and $6,000. If you notice a fuzzy or duplicated image on your Minnesota quarter, don’t toss it aside—you might be holding something worth far more than 25 cents.

4. 2008 Alaska Quarter – Rare Proofs in Circulation

This coin showcases a bold image of a grizzly bear capturing a salmon, representing Alaska’s untamed wilderness and thriving wildlife. While the standard version is common, a few ultra-rare proof coins—which are meant for collectors and not everyday transactions—have somehow entered general circulation.

These proof quarters are easily recognized by their shiny, mirror-like finish and sharp, crisp details. They’re not typically found in pocket change, but when they do show up, they can be worth a significant sum—sometimes hundreds or even thousands of dollars. If your Alaska quarter appears extra glossy and perfectly struck, it could be one of these rare proof coins.

5. 2000 New Hampshire Quarter – Proof Error Coins

Featuring the Old Man of the Mountain, a famed rock formation that sadly collapsed in 2003, the 2000 New Hampshire Quarter carries sentimental value. But its real draw for collectors lies in the mistakenly released proof versions—high-quality coins that were never meant to circulate.

These proof error coins are different from regular quarters due to their high-definition imagery and polished finish. When one ends up in general use, it becomes a rarity that attracts significant attention from numismatists. Some of these proof error quarters have sold for as much as $500, making them a worthwhile discovery for those who pay close attention to their change.
