Are 1990-D Washington Quarters with “mint mark errors” really worth $1,000+? 🤔 Let’s break it down and see which ones are truly valuable, and which ones are just hype.
At PennyVerse.info, we’ve studied hundreds of these coins, and here’s the full guide for collectors and sellers.
🔍 What Collectors Claim to Find
Many listings online talk about two major 1990-D quarter errors:
- “Double Die Mint Mark” – ⚡ extremely rare (and often faked)
- “Die Clash on Wing” – 🦅 more common but still collectible
But here’s the problem 👉 many sellers list coins with no certification, vague descriptions, or even stock photos. 🚩
📊 Real Market Value of 1990-D Quarter Errors
Here’s what you can actually expect to get in today’s market:
| Error Type | Certified Value (PCGS/NGC) | Raw Coin Value |
|---|---|---|
| ✅ True Double Die Mint Mark | $300 – $1,500 | $50 – $200 |
| 🦅 Die Clash on Wing | $50 – $150 | $10 – $30 |
| 🔥 Combination Errors | $500+ (if verified) | $100 – $300 |
💡 Pro Tip: A real double die mint mark will show clear separation lines under 10x magnification. Most eBay “errors” are just machine doubling (worth very little).
✅ How to Spot a Real 1990-D Quarter Error
- 🔎 Check the Mint Mark: Look under a 10x loupe for true doubled features, not flat shelf-like marks.
- 📖 Compare with PCGS CoinFacts: Only trust errors that match known examples.
- 🦅 Die Clash Signs: Look for faint mirror-image outlines of the eagle’s wings on the obverse.
- ⚖️ Test Weight/Size: A genuine quarter should weigh 5.67g and measure 24.26mm.
🚨 Warning Signs of Fake Listings
Be cautious when you see:
❌ “Rare error” claims with no certification
❌ Stock images instead of real coin photos
❌ Sellers who don’t accept returns
❌ Overuse of “double die” with no proof
