A small mistake can sometimes lead to a big payday—especially in the world of coin collecting. One such case involves a tiny minting error on a U.S. quarter that transformed a seemingly ordinary coin into a collector’s dream. This single flaw made the quarter incredibly valuable, fetching tens of thousands of dollars at auction. If you have old change lying around, it may be time to take a second look—especially at your quarters.
2004 Wisconsin Extra Leaf Quarter
One of the most famous mint errors in modern quarters is the 2004-D Wisconsin State Quarter with an Extra Leaf. Due to a die error, some coins were struck with an extra leaf on the left side of the ear of corn. There are two varieties: the “Extra Leaf Low” and the “Extra Leaf High.” These coins appeared in very limited numbers and sparked a frenzy among collectors. Depending on condition, these quarters can sell for $300 to over $6,000, and rare, uncirculated examples may fetch even more.
1970-S Washington Quarter Overstruck on a 1941 Canadian Quarter
This bizarre and extremely rare error involves a 1970-S Washington Quarter that was accidentally struck over a 1941 Canadian Quarter. This double-denomination error is extremely unusual and likely occurred during a planchet mix-up at the mint. Only one known example has surfaced, and it sold for nearly $35,000 at auction. The coin shows partial details from both the U.S. and Canadian coin, making it a truly unique collector’s item.
1999-P Connecticut Broadstrike Quarter
A more subtle but still valuable mint error is the 1999-P Connecticut Broadstrike Quarter. This error occurs when the coin is struck without the collar that normally shapes it, causing it to spread wider than a typical quarter. These broadstrike errors don’t involve a missing design but rather a distortion of shape. A Connecticut State Quarter with this flaw can be worth $50 to $500 or more, depending on how dramatic the error is and its condition.
It’s incredible how a small mistake—barely noticeable to the average person—can make a coin worth thousands of dollars. The 2004 Extra Leaf Quarter, the 1970-S Overstruck Quarter, and the 1999 Broadstrike Connecticut Quarter are proof that mint errors are more than just factory defects—they are prized rarities. Collectors hunt for these coins because they represent a break from perfection and a slice of history. So before you spend that quarter, give it a closer look—it could be worth a fortune.
