What if the loose quarters in your pocket weren’t ordinary change—but hidden treasures worth thousands or even hundreds of thousands of dollars?
Some of the most valuable U.S. quarters ever discovered look completely normal at first glance. But subtle mint errors, rare compositions, and positioning mistakes have turned everyday coins into auction legends.
Below is a step-by-step guide to the most shocking Washington quarter discoveries collectors are hunting right now 
1973 Washington Quarter — Date Touching the Edge Error

This rare error occurs when the date “1973” is struck dangerously close to the rim—sometimes touching it.
Why It’s Valuable:
- Caused by die or planchet misalignment
- Extremely hard to fake
- Rare for 1970s coins due to tighter Mint quality control
What to Check:
- Look closely at the date position
- The closer it is to the rim, the higher the value
- Condition matters, but even circulated examples can sell for thousands
One sharp example reportedly exceeded $15,000 at a premium coin show.
