At PennyVerse.info, we dig deep into overlooked U.S. coins that could turn into life-changing finds. And the 1990-D Washington Quarter is no exception. Some collectors believe that a rare combination of minting errors on a single coin—double-die mintmark, die clash, and “spitting eagle” chip—could push its value into seven-figure territory.
Could your 1990-D quarter hold the key to a million-dollar payday?
🔎 The $1.5M Error Combination: What to Look For
While a typical 1990-D quarter is only worth face value, one with these ultra-rare error combinations may be worth up to $1,500,000, if authenticated and graded in top condition:
1. Double-Die Mintmark (🎯)
- What it is: The “D” mintmark shows a clear, separated doubling.
- How to spot it: Use a 10x–20x magnifier. Look for distinct split lines—not blurry, flat doubling (that’s machine doubling).
2. “DD Wing” Die Clash (🦅)
- What it is: Obverse and reverse dies struck each other without a blank coin in between, transferring ghost-like details.
- How to spot it: Look for traces of Washington’s face or letters appearing faintly near the eagle’s wings.
3. “Spitting Eagle” Die Chip (🗣️)
- What it is: A raised die chip that appears like a spit stream from the eagle’s beak.
- How to spot it: Use close-up images. Look for a small, raised line or dot near the mouth.
🧠 True Errors vs. Worthless Damage – Know the Difference
| Type | Value? | Description |
|---|---|---|
| Doubled Die | ✅ Yes | True minting error caused by die misalignment |
| Die Clash | ✅ Yes | Mis-strike imprinting part of the opposite design |
| Die Chip (“Spit”) | ✅ Yes | Caused by die damage; raised area, not post-mint damage |
| Machine Doubling | ❌ No | Flat, shelf-like doubling—not collectible |
| Post-Mint Damage | ❌ No | Scratches, dings, or tool marks—no added value |
💎 Condition = Cash: The Power of Grading
To unlock full market value, your coin’s condition matters:
| Grade | Condition | Impact on Value |
|---|---|---|
| Circulated | Worn, but error visible | Some value |
| AU-50 | Light wear, some luster | Higher premium |
| MS-63 | Mint State, minor marks | Strong value |
| MS-65+ | Nearly perfect, brilliant luster | 💰 Top-tier pricing potential |
| MS-67+ | Flawless, museum quality | 🔥 Could break auction records if errors exist |
