Our Mission: Redefining the Standard for Alternative Asset Valuation
Our Commitment: Education Without Barriers
At Variety Errors, we believe that expert knowledge should be a right, not a luxury. While others build paywalls, we build bridges. We are committed to keeping our resources free and accessible to all, providing the same professional-grade data and Alternative Asset Valuation that others charge for, at no cost to our community.
Our mission extends beyond the screen; we actively support educational programs and charities to ensure the next generation of collectors has the tools they need to succeed. We aren’t just tracking markets—we’re investing in people.
We believe that every collection is an investment. In a rapidly shifting market, collectors need more than just a hobbyist’s guide—they need high-fidelity data and institutional-grade tools.
Our mission is to provide the definitive Collectibles Market Index, empowering collectors to audit, analyze, and grow their portfolios with the same precision used in traditional financial markets.
The V.E.R.A. System: Data-Driven Rarity
The heart of our platform is the Variety Errors Rarity Aggregator (V.E.R.A.). Born from a need for real-time accuracy, V.E.R.A. is a proprietary lookup tool designed specifically for banknote serial numbers from 1950 to the present. (Future tools and apps are one the way for older, obsolete and error currency valuation.)
By aggregating production data and market trends, V.E.R.A. provides instant Asset Valuation, delivering three-tier pricing for:
Circulated specimens
High-Grade Circulated examples
Professionally Graded banknotes
A Complete Collectibles Ecosystem
Beyond our software, Variety Errors serves as a comprehensive hub for serious numismatists and investors:
Precious Metals Index: Real-time tracking for bullion and market-shaping trends.
The Online Store: A curated marketplace for rare collectibles, professional tools, and numismatic supplies.
The Archive: Digital access to the most comprehensive variety and error database in the industry.

His goal remains the same today as it was at the start: to provide the community with the truth, for free, one serial number at a time.
Hello. My name is Robert, and I have a very unique twenty-dollar bill. It is a 2013 series, and on the left side of Jackson’s head, there is the number 500 running down towards his temple. It looks like it was printed by mistake, and I have never seen another bill like it. The serial number on it is MJ43100399C. There is also the mark of J10 just below the serial number on the upper left-hand side in the front. The 500 on Jackson’s head is clearly visible on the backside when held up to the light, and it is obvious that it was printed onto the bill. If you are interested in the bill, I can be reached at *************. Thank you.
Sorry for the late reply! That sounds like a really unique printing error on your 2013 $20 bill, especially with the “500” on Jackson’s head and the J10 mark. Errors like this can be valuable depending on condition and collector interest. For your safety, please don’t share your phone number publicly online. If you want, you can send detailed photos to a trusted currency expert or check resources like varietyerrors.com for more info. Thanks for sharing!
Hi,
I have a question: On facebook I see plenty of films where errors on coins get shown, also here on your webpage. I am new in that area, but I like it, it is interesting. So when I find some errors in coins, how can I make cash out of them ? Sometimes it is only a relative small amount what I would get, so it is not worth sending this coin to PCGS or NGC for grading, as the grading would cost more than I would be able to cash in on some coins.. – and I saw Ebay is overloaded with tons of error coins who are waiting to get a buyer for a very long time..
And my nearest coin shop is only interested in very high value coins, so I have not yet found any double dies, which might have a high value, not even after looking through around 200 penny rolls so far.. Greetings, Peter
Absolutely, Peter — great question and welcome to the hobby. You’re not alone; a lot of folks start exactly where you are: seeing cool errors online, finding some interesting coins in circulation, and wondering how to actually turn that into cash.
Here’s the honest breakdown:
You’re 100% right that not every error coin is worth grading, especially with grading fees starting around $30–$70 once you factor in shipping, insurance, and membership. So when a coin might only sell for $10–$20, grading it would actually cost you money, not make you money.
What you can do in those cases is sell them raw (ungraded), and there are a few smart ways to go about it:
🔹 1. Sell in small lots or bundles
Instead of listing one $10 coin, try grouping similar low-value errors together—like 10 minor off-centers, or a small mix of die chips, cuds, or misalignments. These lots sell much more easily than individual coins.
🔹 2. Use good photos and honest descriptions
Clear, close-up pictures (front and back, with zooms on the error) and transparent descriptions help you stand out on eBay, Facebook Marketplace, or coin forums. Buyers will scroll past blurry or exaggerated listings.
🔹 3. Join error coin groups on Facebook
Some of the most active and honest buyers are there. Look for groups like Error Coins and Varieties Only or Lincoln Cent Error Group. You’ll see what sells, get fair feedback, and sometimes sell coins without eBay fees.
🔹 4. Look for trusted low-fee alternatives
If eBay feels crowded (which it is), sites like Whatnot, Instagram Lives, or smaller marketplaces like USA Coin Book might give you a better shot at standing out.
As for finding higher-value coins, don’t get discouraged—errors like true doubled dies, rare transitional errors, or coins with strong misalignments do still show up. But they’re rare by nature, so searching 200 rolls without a big find is normal, not a failure.
