Did you know that some U.S. quarters are worth way more than 25 cents? Thanks to minting errors, ordinary coins can become extraordinary treasures, with some selling for over $100,000!
Minting errors happen when mistakes are made during the coin production process, and collectors absolutely love them.
Let’s take a look at three rare and valuable quarters made special by these unique mistakes.
The 1932-D Washington Quarter (Doubled Die Reverse)
The 1932-D Washington Quarter is already a rare coin, but a special version with a “doubled die reverse” makes it one of the most valuable quarters ever.
So, what’s the deal with this error? The die used to stamp the back of the coin was misaligned, creating a “doubled” appearance on the design.
This mistake didn’t happen often, so only a few coins with this error exist. If you find one of these quarters in excellent condition, it could be worth more than $100,000—or even more at auction!
The 1970-S Washington Quarter (No Mintmark)
In 1970, quarters produced at the San Francisco Mint were supposed to have an “S” mintmark. However, a small number of 1970-S Washington Quarters were struck without this mark, turning them into rare collector’s items.
This mistake makes the error coin incredibly desirable. High-quality versions of the 1970-S No Mintmark Quarter have sold for over $100,000, and their value continues to climb.
So, the next time you come across a 1970 quarter, check closely—your spare change could be a small fortune.
The 1964-D Washington Quarter (Overmint Mark)
One of the most famous minting errors, the 1964-D Washington Quarter, features an “overmint mark” error.
Here’s what happened: the Denver Mint accidentally struck a second “D” over the original mintmark on some quarters. This type of mistake is rare, and collectors love it! A 1964-D Quarter with an Overmint Mark in high-grade condition can easily fetch more than $100,000.
This coin is a must-have for error coin enthusiasts, and it’s one of the most talked-about minting mistakes in history.
Why Minting Errors Are So Valuable
Minting errors like these don’t just make coins unique—they also make them priceless to collectors.
The 1932-D Doubled Die Reverse, the 1970-S No Mintmark, and the 1964-D Overmint Mark are perfect examples of how small mistakes can turn ordinary coins into incredible treasures.
If you think you’ve found an error coin, it’s worth getting it checked by a professional. You never know—it might just be worth a fortune!
