In the realm of numismatics, few discoveries ignite as much excitement as finding a valuable error coin. For collectors and enthusiasts alike, the 2010 penny holds a special allure, with certain rare errors transforming these humble cents into prized possessions worth hundreds or even thousands of dollars. This comprehensive guide delves deep into the world of 2010 penny errors, offering expert insights to help you identify these hidden gems and understand their true value in today's market.
The Minting Process and How Errors Occur
Before we explore specific errors, it's crucial to understand how these mistakes happen during the minting process. The U.S. Mint produces billions of coins annually, and while their quality control is generally excellent, errors do occasionally slip through.
The basic steps of coin production are:
- Blank preparation
- Annealing (heat treating)
- Upsetting (creating the rim)
- Striking (imparting the design)
Errors can occur at any of these stages, resulting in coins with unique characteristics that deviate from the intended design or composition.
Top 10 2010 Penny Errors and Their Values
1. Broad Struck Error
What to look for: A penny with an increased diameter and a thinner edge.
This error occurs when the coin planchet is struck outside the collar that normally contains it. The result is a wider, flatter penny with a distinctive appearance.

- 2010-D Lincoln Cent, MS63: $650 (eBay, 2019)
2. Strike Through Error
What to look for: Unusual impressions or textures on the coin's surface.
This happens when a foreign object gets between the die and the planchet during striking, leaving its impression on the coin's surface.
Recent sales data:
- 2010-D Lincoln Cent with retained strike through, MS60: $980 (Great Collections, 2017)
- 2010-P Lincoln Cent with fabric strike through, MS64: $550 (Heritage Auctions, 2018)

4. Clashed Die Error
What to look for: Faint impressions of the opposite side's design on either face of the coin.
Clashed die errors happen when the obverse and reverse dies strike each other without a planchet between them, transferring some of their design to each other.
Recent sales data:

5. Die Crack Error
What to look for: Raised lines or cracks on the coin's surface.
Die cracks form as the die wears down, creating raised lines on the struck coins.
Recent sales data:
- 2010-P Lincoln Cent, obverse and reverse die cracks, MS65: $810 (Great Collections, 2018)
- 2010-D Lincoln Cent, major obverse die crack, MS64: $550 (Heritage Auctions, 2020)
6. Die Cap Error

Identifying Error Coins: Expert Tips
As a seasoned coin collector, I've developed several techniques for identifying error coins:
- Use proper lighting: Natural daylight or a balanced LED light source is ideal.
- Employ magnification: A 10x loupe is sufficient for most errors, but a USB microscope can be helpful for subtle varieties.
- Compare to known examples: Build a reference collection of normal coins for comparison.
- Learn die characteristics: Familiarize yourself with how dies wear and the resulting effects on struck coins.
- Join a numismatic organization: Groups like the Combined Organizations of Numismatic Error Collectors of America (CONECA) offer valuable resources and expertise.
Preserving and Protecting Your Error Coins
Once you've identified a valuable error, proper preservation is crucial:
- Handle coins by their edges using cotton gloves.
- Store in non-PVC, inert holders designed for long-term coin storage.
- Maintain a stable environment: avoid extreme temperatures and humidity.
- Never clean your coins: improper cleaning can significantly reduce value.
- Consider professional grading for high-value errors (e.g., PCGS or NGC).
The Current Market for 2010 Penny Errors
The market for 2010 penny errors remains robust, with several notable trends:
- Increasing interest in modern errors among younger collectors.
