You've probably seen them at the bottom of a cup holder or sitting in a dusty jar on your dresser. Since 1999, the U.S. Mint has pumped out billions of these things. They’re everywhere. And honestly, because they’re so common, most people assume they’re just worth twenty-five cents.
Most are.
But here is the thing: some of these quarters are actually worth thousands of dollars. We aren't just talking about a couple of bucks for a shiny one. We are talking about "pay off your credit card" kind of money. If you’ve ever wondered how much are state quarters worth in the real world—not just what some hopeful eBay seller says—you need to know exactly what to look for.
Most of the value isn't in the state itself. It's in the mistakes.

The Reality Check: Why Most Are Just 25 Cents
Let’s be real for a second. The U.S. Mint didn't make these to be rare. Between 1999 and 2008, they minted over 34 billion state quarters. When there are billions of something, it’s hard for the price to go up.
If you have a Delaware quarter from your pocket, and it’s been bumped around against keys and other coins, it’s worth exactly 25 cents. Even if it's uncirculated (meaning it looks brand new), it might only be worth $1.25.
Collectors care about rarity and condition. A "normal" quarter that everyone has isn't rare. However, if you have a Silver Proof version—the ones with the "S" mint mark that were sold in special sets—those are worth more because of their 90% silver content. As of 2026, those usually trade for $8 to $40 depending on the state and the current price of silver.
The Big Winners: Error Quarters That Pay Out
This is where things get interesting. If a machine messes up at the Mint, it creates a "variety" or an "error." These are the coins that make the news.
The Famous Wisconsin "Extra Leaf"
The 2004-D Wisconsin quarter is the king of state quarter errors. On the back, there’s a corn stalk. On some coins, there’s an extra leaf that looks like it was drawn on by a ghost. There are two types: the "High Leaf" and the "Low Leaf."
- High Leaf: The extra leaf is higher up, nearly touching the corn.
- Low Leaf: The leaf is lower, touching the cheese wheel.
In 2026, a High Leaf in great condition can still fetch anywhere from $100 to $300, and perfect specimens have gone for much more at auction.
1999 Delaware "Spitting Horse"
The very first state quarter has a funny one. Caesar Rodney is on a horse, and a die crack (a literal crack in the metal stamp) makes it look like a line of spit is flying out of the horse’s mouth. It's subtle. You might need a magnifying glass.
- Value: It’s not a retirement-fund coin, but it’s worth about $10 to $50 if it’s in decent shape.
2005 Kansas "In God We Rust"
This is a fan favorite because it’s hilarious. Grease sometimes gets stuck in the coin die. On some Kansas quarters, the grease filled the letter "T" in "Trust." The result? A coin that says "In God We Rust."
- Value: These usually sell for $30 to $100 depending on how clear the error is.
The "Extra Tree" Minnesota Quarter
Minnesota has a lot of trees on the back. Sometimes too many. There are dozens of "doubled die" versions where an extra tree (or part of one) appears to the right of the state outline.
- Value: Some of these are common and worth maybe $5, but the "WDDR-01" variety (the most obvious extra tree) can hit **$100 or more** in Mint State 65.
The "Holy Grail" Errors: Thousands of Dollars
If you really want to know how much are state quarters worth at the top end, you have to look for the stuff that looks totally wrong.

- Experimental Planchets (1999): Before the Mint settled on the metal for the golden Sacagawea dollar, they tested the alloy on state quarter dies. If you find a 1999 quarter (usually Delaware, Pennsylvania, or Georgia) that looks gold or greenish-yellow and weighs more than a normal quarter, you’re sitting on a goldmine. These have sold for $3,000 to $10,000.
- Struck on a Nickel: Sometimes a nickel blank (planchet) gets into the quarter machine. The coin will be smaller, thinner, and missing the edges of the design. A 2000 Maryland quarter struck on a nickel recently sold for over $500.
- Missing Clad Layer: Quarters are sandwiches of nickel and copper. If the "bread" (the nickel) falls off before it's struck, you get a coin that is bright copper red on one side. These "missing clad" errors are worth $200 to $500.
How to Check Your Change Like a Pro
If you're going to start hunting, don't just squint at every coin. You'll go crazy. Here is how experts do it:
Weight is everything. A normal state quarter weighs 5.67 grams. If yours weighs 5.9 grams or 5.0 grams, something is up. It might be an experimental planchet or a wrong-metal error. Get a cheap digital scale that measures to two decimal places.
Look at the edges. If you see a solid copper edge with no silver/nickel "sandwich" look, it’s probably a missing clad layer. If the edge is smooth instead of reeded (the little bumps), it might be a "Broadstrike" error, where the coin spread out like a pancake because it wasn't held in place.
The "S" Mint Mark. Flip the coin to the front (Washington's side). Look for the tiny letter to the right of his ponytail.
- P means Philadelphia (Common)
- D means Denver (Common)
- S means San Francisco (Proof - usually silver or special collector edition)
If you find an "S" quarter in your pocket change, someone probably spent their parent's coin collection. Keep it. It’s worth more than 25 cents just for the silver or the low mintage.
What to Do if You Find Something "Real"
Don't clean it. Seriously. This is the biggest mistake beginners make. They find a 2004 Wisconsin Extra Leaf and think, "I'll just scrub this with some baking soda to make it shine."
You just destroyed the value.
Collectors want the original surface, even if it’s a bit dull. If you think you have a high-value error, put it in a small plastic bag or a coin flip to keep it from getting scratched.
Your next move should be to check "Sold" listings on eBay—not the "For Sale" listings. People can ask for a million dollars for a Cheeto; it doesn't mean it sells. Filter by "Sold Items" to see what people are actually paying in 2026. If the prices are consistently high, it’s time to look into professional grading from companies like PCGS or NGC. A certified grade is the only way to get the true top-tier value for a rare error.
Start by grabbing a magnifying glass and a small digital scale. Focus your search on the 1999 Delaware, the 2004 Wisconsin, and the 2005 Kansas quarters first, as these are the most recognizable and easiest to sell to a local coin shop.
