How a Modern Minting Error Created a Six-Figure Rarity
The Coin That Broke the Rules
Your image reveals an extraordinarily rare 1999 Washington Quarter featuring:
- “ITIBERTY” & “IBERTY” (double-struck lettering)
- Double-dated “1999” (misaligned secondary impression)
- “Erepo” on the reverse (partial mirror brockage error)
Only 3-5 examples of this specific double-strike error are confirmed, making it one of the most valuable modern errors.
Key Identification Features
Obverse Errors:
- “ITIBERTY” (first strike) overlapping “IBERTY” (second strike)
- Faint “1999” visible above/below the primary date
- Distorted Washington profile from misaligned die
Reverse Errors:
- “Erepo” (partial inverted text from a brockage strike)
- Extra leaf lines on the wreath
Authenticity Checklist:
Weight: 5.67g (standard for clad quarters)
Diameter: 24.26mm
Magnetic? No (modern quarters are nickel-copper clad)
Edge: Reeded, with possible flattening from the error
Market Value (2024 Estimates)

Documented Sale:

Red Flags (Fakes Are Everywhere!)
“LIBERTY” spelled correctly (real errors show overlapping text)
No doubling on date (authentic coins have clear secondary impressions)
Smooth edges (genuine errors often show flattened reeding)
How This Error Happened
This coin was likely:
- Struck normally, then jammed in the press
- Re-struck at an angle, creating overlapping text
- Brockage transfer from another coin caused the reverse “Erepo”
The Mint’s quality control usually catches these—but a few escape.
Why Collectors Crave It
