You’re staring at a Benjamin. It looks weird. Maybe the serial numbers aren’t level, or the green seal is wandering toward the edge of the paper. Most people would just try to spend it as fast as possible, fearing it’s a counterfeit. That is a massive mistake. A misprinted 100 dollar bill is often worth significantly more than its face value, sometimes reaching the price of a used sedan at auction. It’s the ultimate irony of the U.S. Treasury: their failure is your fortune.
The Bureau of Engraving and Printing (BEP) is actually incredibly good at its job. They churn out billions of notes with surgical precision. Because their quality control is so tight, the stuff that slips through the cracks becomes an instant rarity. Collectors, or "notaphilists" if you want to be fancy about it, go absolutely nuts for these things. We aren't just talking about a little smudge. We are talking about fundamental structural errors in the printing process that make a bill unique.
What Actually Makes a Misprinted 100 Dollar Bill Valuable?
It’s about the "how." How did the machine mess up? The value of a misprinted 100 dollar bill is tied directly to the complexity of the printing stage where the error occurred. U.S. currency is printed in three distinct stages. First, the back of the bill. Second, the front (the face and the fine detail). Third, the "overprinting," which includes those green serial numbers and the Treasury seals.
If you find a bill where the third printing is upside down—known as an Inverted Overprint—you’ve hit a minor jackpot. Why? Because it’s obvious. It’s dramatic. Collectors pay for drama. A bill that looks like it went through a blender and came out as a "butterfly fold" (where the paper was folded before being cut) can fetch five figures. Honestly, it’s kinda wild that a piece of paper meant to represent $100 can suddenly represent $10,000 just because a machine got a paper jam in 2013.

The Great 2010 Series Debacle
Let’s talk about the big one. The 2010 Series $100 redesign was a nightmare for the BEP. They introduced the "3D Security Ribbon" and the "Bell in the Inkwell." These were high-tech features meant to crush counterfeiters. Instead, they crushed the printing presses. The paper started creasing.
Because the paper was folding over on itself during the run, massive amounts of these bills had blank white streaks through them once they were unfolded. We are talking about $110 billion worth of currency that had to be quarantined. Some of these "mismade" 100s escaped into the wild. If you find a Series 2009 or 2010 misprinted 100 dollar bill with a vertical white gap where the ink didn't hit, you aren't looking at a damaged bill. You are looking at a manufacturing defect from one of the most expensive printing errors in American history.
Identifying Real Errors vs. Garage Alterations
You’ve gotta be careful. People are sneaky.
A real error happens at the mint. A fake error happens in someone's basement with a chemical solvent or a home printer. If you see a "missing" seal, check if the paper is thin or fuzzy in that spot. Fraudsters use chemicals to bleach away the seals to try and create a "missing print" error. Real errors will have crisp, undisturbed paper fibers.
- Cutting Errors: These happen when the large sheets of bills are sliced incorrectly. You might see part of the next bill’s border on your note. These are common, so they don’t pay out as much as you’d think, maybe $150 to $300 for a hundred-dollar note.
- Ink Smears: Exactly what it sounds like. A giant blob of green or black ink. If it covers a key feature like Franklin’s face, the value goes up.
- Gutter Folds: These are the white vertical lines I mentioned earlier. The paper folds, gets printed, then unfolds.
- Double Denominations: The Holy Grail. This is when a bill is printed as a $100 on one side and, say, a $50 or a $10 on the other. If you ever find one of these, stop. Don't fold it. Put it in a hard plastic sleeve immediately.
Heritage Auctions and PCGS (Professional Coin Grading Service) handle these high-end rarities. They’ve seen bills sell for more than some people make in a year. One famous "Del Monte" $20 bill, which had a literal banana sticker printed under the ink because it fell onto the paper at the mint, sold for nearly $400,000. While a misprinted 100 dollar bill might not always reach those heights, the potential is there.
The Paper Matters
The feel of the paper is your first clue. U.S. currency isn't actually paper; it's 75% cotton and 25% linen. If you find a misprinted 100 dollar bill that feels like standard copier paper, it’s just a bad fake. But if the texture is right—that distinct, slightly abrasive "raised ink" feel—and the image is shifted or doubled, you're in business.
The "Series" year is also a huge factor. Collectors often look for errors in newer series because the technology is supposed to be "error-proof." When the new blue-ribbon 100s came out, everyone was looking for mistakes. Those early errors from the 2009A series are still some of the most sought-after modern notes because they represent a specific moment when the government’s reach exceeded its grasp.
Double Prints and Ghost Images
Sometimes the sheet doesn't feed right and gets hit twice by the same plate. This creates a "Double Impression." It looks like the bill is vibrating or like you’re looking at it through 3D glasses without the tint. It’s disorienting. It’s also worth a lot of money. Unlike a "doubled die" coin, which is a mistake on the stamp itself, a double-printed bill is usually a unique occurrence on that specific sheet.
How to Cash In Without Getting Ripped Off
Don't go to a pawn shop. Just don't. They’ll offer you $120 for your misprinted 100 dollar bill and then laugh while they sell it for $1,200.
If you think you have a genuine error, your first step is authentication. Organizations like PMG (Paper Money Guaranty) are the industry standard. You send them the bill, they verify it’s real and not "doctored," and they give it a grade from 1 to 70. A "Gem Uncirculated 65" error note is the dream. Once it’s in that plastic "slab" with a certified grade, its value is essentially locked in and verifiable.

Selling at a dedicated currency auction is usually the move. It brings out the big spenders who are looking for that one specific "gutter fold" to complete a collection. You’ll pay a commission, sure, but the final price will be way higher than what you’d get on a local listing site.
Actionable Steps for the Lucky Finder
If you find a misprinted 100 dollar bill in the wild, follow these steps to preserve its value:
- Handle with Care: Use tweezers if you have them. Oils from your skin can degrade the paper and lower the grade from a "70" down to a "50" in seconds.
- No Ironing: Do not try to "fix" a fold or a wrinkle. You will destroy the paper fibers and kill the collector value.
- Check the Serial: Look at the serial numbers. Sometimes an error bill also has a "fancy" serial number (like 00000001 or 12345678). This is a "double whammy" and can multiply the value exponentially.
- Sleeve It: Buy a PVC-free currency sleeve. You can get them for a couple of bucks at any hobby shop. This prevents the bill from getting further "circulation wear."
- Search the Heritage Auctions Database: Look up your specific type of error (e.g., "100 dollar bill offset printing error") to see what similar notes have actually sold for in the last two years. This gives you a realistic baseline for what you’re holding.
- Get a Professional Opinion: Contact a reputable dealer who belongs to the American Numismatic Association (ANA). They have a code of ethics they have to follow, making them a much safer bet than a random "We Buy Gold" storefront.
Owning a misprinted 100 dollar bill is like owning a piece of a glitch in the federal system. It’s a rare moment where a mistake by a massive government entity actually puts money into your pocket instead of taking it out. Keep your eyes on your change; most people are too busy looking at their phones to notice a fortune passing through their hands.
