State quarters have long been a favorite among collectors, but did you know that some of these coins are worth a fortune? While most quarters in circulation are worth just 25 cents, a select few rare and error-state quarters have fetched astonishing prices at auctions, some reaching up to $6.7 million! If you have a jar of spare change lying around, it’s time to take a closer look you might be sitting on a hidden treasure. Here are the top five rare state quarters that could be worth a fortune.
1. 1999-P Delaware State Quarter (Spitting Horse Error) – Worth Up to $35,000
The Delaware state quarter, released in 1999 as part of the U.S. Mint’s 50 State Quarters Program, is one of the most famous error coins. This quarter features an image of Caesar Rodney on horseback. However, a unique minting error, known as the “Spitting Horse” error, has significantly increased its value.
What to Look For:
- A visible raised line extending from the horse’s mouth, resembling spit.
- The error is caused by a die crack in the minting process.
- Coins in mint condition with this error can fetch thousands of dollars at auctions.
While not the most valuable quarter on this list, if you find one in pristine condition, you could be looking at a hefty payout.
2. 2004-D Wisconsin State Quarter (Extra Leaf High and Low) – Worth Up to $125,000
The 2004 Wisconsin quarter is another rare find that has collectors searching through their loose change. This coin was released to honor the state’s agricultural heritage, featuring a cow, a wheel of cheese, and an ear of corn. However, due to a minting error, some coins have an additional leaf on the corn stalk.
What to Look For:
- Two variations exist: “Extra Leaf High” and “Extra Leaf Low.”
- The extra leaf appears on the left side of the corn stalk.
- High-grade versions of this quarter have sold for over $100,000 at auction.
If you find one of these rare quarters in your collection, it could be worth a life-changing amount of money.
3. 1999-P Connecticut State Quarter (Experimental Planchet) – Worth Up to $1.2 Million
The 1999 Connecticut quarter is another highly sought-after coin due to an experimental planchet error. Planchets are the blank metal discs used to mint coins, and during the production of the first state quarters, a few were struck on experimental metal compositions.

- Some versions were struck on experimental planchets.
- A certified coin with this error once sold for nearly $3 million.
This quarter is incredibly hard to find, but if you happen to have one, you could be sitting on a small fortune.
5. 2000-P Maryland State Quarter (Double Struck Error) – Worth Up to $6.7 Million

How to Determine the Value of Your Quarters
If you think you might have one of these rare state quarters, follow these steps to determine its value:
- Examine the Coin Closely – Use a magnifying glass to check for errors such as die cracks, double strikes, or extra details.
