Coin collecting is one of the oldest and most rewarding hobbies, but among the broad categories within numismatics, few spark as much curiosity and excitement as error coins. These are coins that were minted with mistakes—sometimes subtle, sometimes dramatic—that give each one a unique identity. Rather than being worthless misprints, many error coins are highly prized for their rarity, history, and the unusual stories they tell about the minting process. So, the next time you see something unusual in your change, don’t forget to look through the 2023 quarter error list with pictures. Now we will explore the topic of coin mistakes precisely in detail.
What Exactly Are Error Coins?
Error coins are coins that, due to an accidental mistake during the minting process, contain flaws that set them apart from standard, circulation-grade coins. These errors can happen at any stage—die preparation, striking, or even planchet creation—and lead to physical abnormalities. In the world of collecting, such deviations from the norm are often far more valuable than perfection.
Here are some of the most common types of error coins:
| Error Type | Description |
| Double Strike | The coin has been struck more than once, resulting in overlapping images. |
| Off-Center Strike | The coin’s design is not properly aligned, often producing a crescent-shaped blank area. |
| Die Crack/Break | A visible raised line on the coin caused by a crack in the minting die. |
| Wrong Planchet | The coin was struck on a blank meant for another denomination or coin type. |
| Misaligned Die | The obverse and reverse designs are not properly aligned with one another. |
Each error has its own appeal. For example, a 1955 Lincoln cent with a dramatic doubled die obverse is a dream find for many collectors and has sold for thousands of dollars at auction.
Why People Collect Error Coins
The appeal of error coin collecting lies in its combination of mystery, education, and financial opportunity. Unlike regular coins, which are produced in the millions with high uniformity, error coins are rare by nature. This rarity drives demand—and often, value.
Here’s why more collectors are diving into this niche:
- Rarity and Value: Most error coins are one-offs or part of extremely limited batches. Their scarcity naturally makes them more desirable and often more valuable.
- Historical Intrigue: Each error tells a story about how the coin was made, reflecting a snapshot of a moment when something in the minting process went unexpectedly wrong.
- Engaging Challenge: Collectors enjoy the detective-like challenge of spotting errors that others might overlook—especially when they’re hidden in plain sight among regular coins.
In essence, collecting error coins isn’t just about building a portfolio—it’s about uncovering hidden gems that connect the past and present in the most tangible way.
The Evolution of Error Coin Identification
Traditionally, spotting error coins relied on years of hands-on experience, careful visual inspection under magnification, and referencing exhaustive coin catalogs. But today, technology has revolutionized how collectors find and identify errors, giving even beginners the tools to compete with seasoned pros.
Modern apps and online tools can now help detect errors with incredible precision. And leading this tech-forward movement is the Coin ID Scanner app, which we’ll explore more in the next section. With AI-driven identification, large-scale coin databases, and real-time market data, this app has made error coin collecting more accessible, efficient, and exciting than ever before.
How to Identify Error Coins: A Modern Approach
While magnifying glasses and printed coin guides still have their place, today’s collectors benefit from far more advanced methods. Identifying an error coin involves analyzing tiny visual discrepancies—some almost invisible to the untrained eye. That’s where technology steps in to bridge the gap.
Enter the Coin ID Scanner app — a revolutionary tool designed to help collectors of all levels accurately identify, assess, and manage coins, including rare error varieties.

Pro Tip: When using the app, ensure good lighting and a clean background for best image accuracy. Coins with dirt, heavy wear, or shadows may affect scanning precision.
Tips for Successfully Collecting Error Coins
Whether you’re a beginner or already have a few errors tucked away in your album, applying smart collecting strategies can boost your success rate and increase the satisfaction of every find.
1. Educate Yourself About Error Types
Start by understanding the various classes of mint errors. This includes:
- Planchet Errors: Wrong metal, clipped planchets, or improper thickness.
- Die Errors: Cracks, cuds (missing die chunks), or doubled dies.
- Strike Errors: Off-center, misaligned dies, or multiple strikes.
Online courses, numismatic forums, and auction listings are gold mines of real-world examples and discussions.
2. Use the Right Tools
While the Coin ID Scanner app should be your first go-to, it helps to also have:
- A 10x magnifying glass or jeweler’s loupe.
- A caliper for measuring coin thickness.
- A digital scale for verifying proper weight.
3. Document and Organize
Keep detailed records for each error coin:
- High-resolution photographs (both sides)
- Description of the error type
- Date and place of acquisition
- Estimated market value and source of appraisal
Apps like Coin ID Scanner simplify this by offering built-in cataloging features.
4. Verify and Grade Your Error Coins
While apps offer instant value estimates, professional grading services like PCGS or NGC provide authentication, error confirmation, and certified valuation. This step is crucial for high-value coins and for selling your collection in the future.
5. Follow Market Trends
Like other collectibles, error coin values can fluctuate. Stay updated by tracking:
- Auction platforms (e.g., Heritage Auctions, Stack’s Bowers)
- Coin shows and conventions
- Online collector communities on Reddit, CoinTalk, or Discord
The Coin ID Scanner app also integrates updated market pricing, so you’ll know instantly whether a find is trending or undervalued.
Where to Find Error Coins
Error coins can be discovered in unexpected places or deliberately purchased from reputable sources. Here are some of the most effective ways to start or expand your collection:
1. Everyday Pocket Change
Believe it or not, valuable error coins still circulate. Checking your loose change regularly may reveal common errors like off-center strikes or minor die cracks—especially on Lincoln cents, Jefferson nickels, and Roosevelt dimes.
2. Bank Rolls and Coin Hunting
Requesting rolls of coins from banks (a practice known as “coin roll hunting”) can yield surprising results. Look for older coins and anomalies. Combine this habit with the Coin ID Scanner to quickly filter out potential errors.
3. Online Marketplaces
Websites like:
- eBay
- Etsy (for minor collector finds)
- Whatnot
- NumisBids (for serious collectors)
…offer access to both raw and graded error coins. Always check seller ratings and ask for high-resolution images before purchasing.
4. Coin Shows and Auctions
Attending coin shows, trade events, or live auctions allows you to inspect coins firsthand and speak directly with experienced dealers and fellow enthusiasts. Many rare error coins appear here before reaching online markets.
5. Certified Dealers
Reputable numismatic dealers can help you access rarer errors with verified authenticity and grading. Look for dealers affiliated with:
- American Numismatic Association (ANA)
- Professional Numismatists Guild (PNG)
How to Maintain and Protect Your Error Coin Collection
Once you’ve acquired valuable error coins, preservation is essential. Damage, tarnish, or improper handling can reduce even a rare coin’s value.
Best Practices for Error Coin Storage:
| Practice | Why It Matters |
| Use Non-PVC Holders or Capsules | Prevents chemical reactions that damage the coin’s surface. |
| Store in a Cool, Dry Place | Protects against corrosion and environmental wear. |
| Handle with Cotton Gloves | Prevents oils or dirt from your fingers contaminating the coin. |
| Label Clearly | Include the error type, date, and any known provenance. |
| Use Digital Records | Apps like Coin ID Scanner help organize photos, notes, and values. |
Grading companies like PCGS or NGC also offer tamper-proof holders with official designations of the error type, which boosts credibility and resale value.
As digital tools evolve and collector communities become more connected, the landscape of error coin collecting continues to expand. With AI tools like Coin ID Scanner, a wider audience can now access the hobby—bringing in younger collectors, international hobbyists, and even investors seeking rare assets.
Moreover, as error coins gain mainstream attention through viral discoveries and YouTube channels, we’re likely to see even more market activity. Coins with dramatic errors (like the 2000 Sacagawea “wounded eagle” or the 1982 Roosevelt Dime without a mint mark) continue to attract collectors and spike in value.So next time you find a strange coin in your pocket or at a flea market, don’t toss it aside—scan it, study it, and maybe even strike gold.
