Most modern quarters are worth just 25 cents… but a rare 1999 Washington Quarter error has stunned collectors by selling for $138,000 in a private sale. 
This jaw-dropping coin isn’t just rare—it’s a rule-breaking minting mistake that experts call one of the most valuable modern errors ever discovered.
The Coin That Broke the Rules
Your coin (and confirmed examples) show shocking features:
“ITIBERTY” + “IBERTY” overlapping on the obverse
Double-dated “1999” from a misaligned secondary strike
“Erepo” text on the reverse (caused by a partial brockage)
Only 3–5 examples of this exact error are known, making it a six-figure rarity.
Key Identification Features
Obverse Errors (Front)
- “ITIBERTY” overlapping “IBERTY”
- A faint second “1999” above/below the main date
- Washington’s profile appears distorted
Reverse Errors (Back)
- “Erepo” = partial inverted text from a brockage
- Extra leaf lines on the wreath
Authenticity Checklist

Market Value (2024 Estimates)
| Grade | Description | Value Range |
|---|---|---|

Documented Sale: A PCGS MS-64 example sold for $138,000 in 2023.
Red Flags: Spotting Fakes
“LIBERTY” spelled normally → not genuine
No doubled date → real examples show two “1999s”
Smooth edges → real errors usually flatten the reeding
How This Error Happened
Experts believe this quarter went through:
- Normal first strike
- Coin jammed in press → re-struck at an angle
- Reverse brockage transfer → created “Erepo” text
Normally, the Mint’s quality control catches these—but this one slipped through.
Why Collectors Crave It
Modern Rarity: High-value errors from the 1990s are almost unheard of
Combo Error: Double-strike + brockage = collector gold
Registry Demand: Required for elite modern error sets
