$2,975 1991 “Double

🔍 A Penny That Shouldn’t Exist

Sometimes the strangest-looking coins end up being the most valuable.
Recently, a 1991 Lincoln penny shocked the coin-collecting community after selling for $2,975 — and when you see what happened to it, you’ll understand why! 👇


💎 The Coin That Shocked Collectors

A collector found a 1991 penny that looked… well, wrong:

🪙 Color: Silver-gray, like a dime instead of copper.
👤 Front Design: You could see Roosevelt’s head faintly overlapping Lincoln’s bust.
🏛 Back Design: Normal Lincoln Memorial reverse — but when flipped, part of Roosevelt’s portrait showed through!

This wasn’t a trick or damage — it was a genuine U.S. Mint blunder worth thousands.


⚙️ What Exactly Is a Double Denomination Error?

This rare minting mistake happens when a struck coin is accidentally fed back into the press and struck again with dies for another denomination.

In this incredible case:

➡️ A 1991 Lincoln cent planchet was struck over a 10-cent Roosevelt dime.
➡️ Both coin designs are visible on one coin — Lincoln and Roosevelt, face to face!
➡️ The result: a unique hybrid error prized by collectors around the world.


🧾 Certified & Sold for Nearly $3,000

The coin was authenticated and certified by a top grading service with the label:

“1991 Double Denomination — Struck on 10¢”

💵 Final Auction Price: $2,975
Yes — one penny brought in almost three thousand dollars! 😱


🧠 How to Spot a Valuable Error Coin

Think you’ve seen something odd in your change? Here’s what to look for 👇

Mixed Designs: Details from two different coins on one side.
Wrong Color: A penny that’s silver, a dime that’s gold, etc.
Unusual Weight or Thickness: Feels slightly heavier or thinner than normal.

👉 If you notice any of these, do NOT spend it!
Instead, have it checked by PCGS or NGC — it could be worth a fortune.
