$9,000 Error Quarter Found!
A rare West Virginia State Quarter was accidentally struck on a copper penny planchet, creating a dramatic mint error that stunned collectors and sold for thousands at auction.
In this guide, you’ll learn exactly why this coin is so valuable, how to spot one step by step, and what to do if you find a similar error in your change.
💰 How a Quarter Becomes a $9,000 Coin
At the U.S. Mint, coin blanks (called planchets) are fed into presses automatically.
Occasionally, the wrong planchet slips into the wrong press.
In this case:
- A penny planchet entered a quarter press
- The quarter design was struck onto copper
- The result was a wrong-planchet error, one of the most desirable mint mistakes
Because these errors are accidental and immediately caught most of the time, very few ever reach circulation.
🔎 Step-by-Step: How to Spot a Quarter Struck on a Penny Planchet
1️⃣ Look for an Unusual Color 🎨
- Normal quarters are silver-gray
- This error coin appears reddish or copper-colored
- The color comes from a pure copper penny blank
👉 A copper-colored quarter should always raise suspicion.
2️⃣ Check the Size 📏
- The coin will be noticeably smaller than a regular quarter
- Penny planchets are thinner and narrower
💡 Place it next to a normal quarter — the difference is easy to see.
3️⃣ Confirm the Design 🏞
Flip the coin and inspect the design:
- If it shows a state quarter design (like West Virginia)
- But is copper-colored and undersized
✅ That’s a strong indicator of a wrong-planchet error.
4️⃣ Weigh the Coin ⚖️ (Most Important Test)
Use a digital scale accurate to 0.01 grams.
| Coin Type | Weight |
|---|---|
| Normal Quarter | 5.67 grams |
| Copper Penny Planchet | ~3.11 grams |
| Error Quarter (Sold) | 3.1 grams |
📌 The weight confirms the coin was struck on a penny blank, not altered later.
