we love helping collectors uncover hidden treasures in their pocket change. The 1967 Washington Quarter is one of those coins where error varieties can turn a simple 25¢ piece into something worth hundreds — or even claims of $100,000+ in extreme cases! 
Here’s how to identify the valuable ones and make sure you don’t overlook a hidden gem.
Why 1967 Quarters Are Special
Special Mint Set Year: In 1967, quarters weren’t produced in regular proof sets — instead, they came in Special Mint Sets (SMS).
Error Potential: Even with tighter quality control, mistakes slipped through. These mint errors are what collectors chase today.
Key Errors to Watch For
1. Doubled Die Reverse (DDR) 
- What to Look For: Doubling on letters or designs on the reverse (back) of the coin.
- Value: $50 – $500+ depending on clarity and condition.
2. Die Chips & Die Breaks 
- What to Look For: Small raised bumps or cracks on the eagle’s wings, body, or arrows.
- Value: $10 – $100+ (larger chips = higher value).
The $100,000 Claim
Some sources suggest that a dramatic, unique mint error on a 1967 Quarter could reach $100,000. While these are rare and often speculative, the fact remains: major mint errors bring serious money.
Quick Spotting Guide: How to Check Your 1967 Quarters
- Check the Reverse (Back)
- Focus on the eagle, arrows, and lettering.
- Look for Doubling
- Words like “UNITED STATES OF AMERICA” or “QUARTER DOLLAR” may show clear, separated double lines.
- Inspect for Chips
- Raised bumps on the eagle’s feathers or arrows.
- Use a Magnifier
- A 10x–20x jeweler’s loupe or USB microscope is ideal.
- Differentiate Error vs. Damage
- Errors are raised (extra metal).
- Damage is incused (scratches, dents, or flattened areas).
How to Maximize Value
- Get It Graded
- PCGS, NGC, or ANACS certification is essential for top-dollar sales.
- Never Clean the Coin
- Cleaning destroys collector value.
- Best Selling Options
- Reputable coin dealers
- Online auctions (Heritage, Stack’s Bowers)
- eBay (works best for graded coins)
