What Are Coin Errors and Why Are They Valuable?
Coin errors are fascinating mistakes that occur during the minting process. These can include misprints, missing features, double impressions, off-center strikes, incorrect planchets, or even unusual metal compositions. Although modern minting techniques are highly advanced and quality control is strict, errors still manage to slip through, often unnoticed by the mint but quickly picked up by collectors.
So why are these errors so valuable? It comes down to a few key factors:
- Rarity: The fewer examples in existence, the higher the demand.
- Visual Appeal: Some errors are so dramatic or odd-looking that they immediately stand out.
- Historical Significance: Certain error coins are tied to specific events or changes in minting practices.
- Grade and Condition: Coins in uncirculated or mint condition can fetch tens of thousands of dollars.
The combination of these factors turns what would otherwise be a simple manufacturing flaw into a highly coveted piece of collectible history.
Let’s take a closer look at the five most valuable coin errors you might just stumble upon in your everyday change.
1. 1937-D Three-Legged Buffalo Nickel (USA)
Arguably one of the most famous U.S. error coins, the 1937-D Three-Legged Buffalo Nickel is instantly recognizable due to its visual oddity. A mistake during die polishing at the Denver Mint removed one of the buffalo’s legs, resulting in a bizarre-looking coin that quickly gained fame in numismatic circles.
Key Facts:
- Year: 1937
- Mint: Denver (D)
- Error: Front leg of the buffalo is completely missing
- Value: From $1,000 in circulated condition to over $50,000 for uncirculated specimens
This coin’s rarity, combined with its unique appearance, makes it a holy grail for U.S. coin collectors.
2. 2008 Undated 20p Coin (UK)
The 2008 Undated 20p Coin is a result of a rare mix-up at the Royal Mint. When the design of the coin changed that year, some coins were accidentally struck using mismatched obverse and reverse dies—leading to coins with no date at all.
Key Facts:
- Country: UK
- Year: 2008
- Error: No date on either side
- Value: Around £50 to £200+, with some fetching even more in top condition
What makes this coin even more special is that it was the first undated British coin in over 300 years.
3. 1955 Doubled Die Lincoln Cent (USA)
This coin is the textbook example of a doubled die error and is well-known even outside numismatic communities. The 1955 Lincoln Cent displays bold doubling of the inscriptions, especially noticeable in “IN GOD WE TRUST,” “LIBERTY,” and the date itself.
Key Facts:
- Year: 1955
- Country: USA
- Error: Visible doubling of text on the obverse
- Value: From $1,500 in fair condition to upwards of $125,000 in mint state
Collectors admire this coin not only for its rarity but for how clear and dramatic the error is.
4. 2011 “Lines Over Face” Aquatics 50p Coin (UK)
As part of the 2012 London Olympics commemorative series, this 50p Aquatics coin was originally minted with wavy lines covering the swimmer’s face. The design was later altered to make the athlete’s face clearer, but a limited number of the original error version made it into circulation.
Key Facts:
- Year: 2011
- Country: UK
- Error: Wavy water lines obscure the swimmer’s face
- Value: Between £1,000 and £2,000 for uncirculated examples
This error is popular among both Olympic memorabilia collectors and traditional coin enthusiasts.
Tip: Look through your 50p coins. The Aquatics one with a swimmer—if the face is obscured by wave lines, you’ve found the valuable version.
5. 2014 £2 Lord Kitchener Coin (UK)
Minted to commemorate World War I, this £2 coin features Lord Kitchener on the reverse. However, a small batch was released without the denomination “Two Pounds” on the obverse, making them rare and valuable.
Key Facts:
- Year: 2014
- Country: UK
- Error: Missing the words “TWO POUNDS” on the Queen’s side
- Value: Ranges from £500 to £1,200 depending on grade and demand
These coins are often overlooked in change, yet they’re highly collectible when authenticated.
How to Check for Coin Errors in Your Change
Searching for error coins can be fun, rewarding, and even profitable. Here’s a beginner-friendly guide to get started:

Step 2: Learn to Recognize Common Error Types
Some of the most frequent (and valuable) errors include:
- Doubled die: Text appears doubled due to misaligned dies
- Off-center strike: Design is not properly centered on the coin

Step 3: Compare with Official References
Use reputable sites to verify what you find:
- PCGS CoinFacts
- NGC Grading Guide
- Royal Mint
Step 4: Store Coins Safely
Use acid-free holders or coin flips to prevent scratches or environmental damage. Avoid handling them with bare hands—use gloves.
