🤯 A $1.5 Million Quarter? Discover the Secret Errors of the 1990-D Washington!

At PennyVerse.info, we don’t just look at coins—we decode potential treasure. That unassuming 1990-D Washington Quarter in your pocket might be more than spare change. Some collectors believe a unique combo of rare mint errors could make this coin worth up to $1,500,000.

Yes, seriously.

Let’s break down the three key errors that make this coin so fascinating—and how to spot them!

🔍 The “Million-Dollar Combo” of Errors

While most 1990-D quarters are worth just 25¢, a specific trio of authentic mint errors could send one into six- or seven-figure territory:

1. Double-Die Mint Mark (“D” Doubling) 🎯

• Where to look: Obverse (front), below “IN GOD WE TRUST.”
• What you’ll see: A clearly doubled “D” mint mark—not smeared or shelf-like.
• Why it matters: A true doubled die is rare, especially on mint marks.

2. “DD Wing” Die Clash 🦅

• Where to look: Reverse (back), near the eagle’s wings and surrounding fields.
• What you’ll see: Ghost-like lines or impressions (e.g., from Washington’s face or “LIBERTY”) transferred onto the reverse.
• Why it matters: Die clash + doubled elements = collector gold.

3. “Spitting Eagle” Die Chip 🗣️

• Where to look: Eagle’s beak on the reverse.
• What you’ll see: A small raised line or lump projecting from the mouth.
• Why it matters: Popular, visual error—often adds value when combined with others.

Die Clash	✅ Yes	Transferred features from the opposite die
Die Chip/Crack	✅ Yes	Raised metal from die damage—collectible in unique spots
Machine Doubling	❌ No	Flat, shelf-like doubling—not a true mint error
