Most people think a hundred dollar bill is just worth, well, a hundred bucks. You hand it to a cashier, they swipe a yellow counterfeit detector pen across Ben Franklin’s face, and you get your change. Simple. But if you’re into currency collecting—or even if you just happen to look closely at your change—you’ll realize the hundred dollar bill value isn’t always a fixed number. Sometimes, a single piece of paper can be worth thousands. Honestly, it’s kinda wild how a tiny printing error or a specific sequence of numbers can turn a standard bill into a goldmine.
Cash is changing. With digital payments taking over, physical notes are becoming a bit of a relic, which actually drives up the "numismatic" value for collectors. We aren't just talking about the gold certificates from the 1920s anymore. Even the "blue stripe" notes you get from an ATM today could have a premium if the serial number hits the right pattern.
The basics of hundred dollar bill value and why it fluctuates
Let's get the boring stuff out of the way first. For 99% of the bills in circulation, the value is exactly $100. That’s the face value. It’s backed by the U.S. government. But the market for "fancy serial numbers" and "error notes" has absolutely exploded on sites like eBay and Heritage Auctions.
Check your serial number. Right now.
If you see something like "00000001," you’ve basically hit the lottery. Low serial numbers are the holy grail. A "Series 2013" $100 bill with a serial number under 100 can easily fetch $500 to $1,000 depending on the condition. Collectors want the first ones off the press. It’s a status thing, but it’s also about rarity. There is only one "00000001" for every prefix.
What makes a bill "fancy"?
It’s not just low numbers. You’ve got "ladders," where the numbers go 12345678. You’ve got "radars," which read the same way forward and backward, like 48822884. Then there are "solid" serial numbers where every digit is the same. A solid 7s hundred dollar bill? That’s a multi-thousand dollar item. People go nuts for those.
Then you have the "Star Notes." You’ve probably seen a little star at the end of a serial number before. That means the original bill was damaged during printing and the Bureau of Engraving and Printing (BEP) replaced it with a new one. Because they don't print many star notes, they are inherently rarer. If you find a star note from a "short run" (where only 320,000 or fewer were printed), the hundred dollar bill value jumps significantly above face value.

History matters: From Gold Certificates to the modern C-note
The $100 bill has been through a lot of makeovers. If you find a 1928 Gold Certificate, you aren't looking at a hundred dollars. You're looking at a piece of history that might be worth $500 even in "circulated" (aka beat up) condition. Back then, you could actually take that bill to a bank and exchange it for $100 worth of physical gold coin. Once the U.S. went off the gold standard, those bills became collector's items.
Then there’s the "Small Size" era. Before 1928, bills were huge—literally "horse blankets." But even the smaller ones from the 1934 or 1950 series carry a premium.
Why?
Mostly because they look cool. They have that classic, old-school greenback vibe that doesn't have the modern "Big Head" Franklin or the 3D security ribbon. Condition is everything here. A crisp, uncirculated 1950 series note is worth way more than one that’s been through a washing machine. Paper quality is a huge factor in the hundred dollar bill value equation. Professional graders like PMG (Paper Money Guaranty) use a 70-point scale. A bill that scores a 65 or higher is considered "Gem Uncirculated."
Error notes: When the government messes up, you win
The BEP is usually really good at its job. But sometimes the machines fail.
Sometimes the paper folds during printing, creating a "gutter fold" where there’s a blank white streak through the middle of the bill. Sometimes the ink from one side bleeds through to the other. Or, my personal favorite: the "mismatched serial number." This is when the two serial numbers on the bill don't match. This happened quite a bit with the Series 2013 notes printed in Washington D.C. and Fort Worth.

If you find a $100 bill where the left serial number ends in a 4 and the right one ends in a 5, don't spend it. That’s a massive error. These "mules" or mismatched notes are incredibly rare and highly sought after by specialists who spend their weekends hunting through bank straps.
The "Blue Ribbon" 2009A and 2013 notes
The modern hundred dollar bill is a marvel of tech. It has a 3D security ribbon woven into the paper, not printed on it. It has color-shifting ink. It has microprinting that you need a magnifying glass to see.
Because these bills are so complex, the error rate actually went up when they were first introduced. There was a famous "crease" issue with the 2009 series that delayed their release for years. Millions of bills were locked in a vault because they were unusable. If one of those "rejected" bills somehow made it into circulation, it’s a collector's dream.
How to check your hundred dollar bill value at home
You don't need to be a pro to figure out if you've got something special. Just follow a few basic steps.
First, look at the "Series" date. It’s usually near the signature. If it’s before 1996 (the year they started making Ben Franklin’s head bigger), it’s worth a closer look.
Next, check the serial number for patterns.

- Binaries: Only 1s and 0s (very popular with tech nerds)
- Birthdays: 12051980 (If someone was born on Dec 5, 1980, they will pay a premium for this)
Third, look at the condition. If the bill has "pinholes" from being stapled or "teller flicks" (tiny bends at the corners), the value drops. Collectors want "EPQ" which stands for Exceptional Paper Quality. They want it to look like it just came off the press five minutes ago.
Where to sell your bills for the best price
If you think you have a high hundred dollar bill value note, don't take it to a pawn shop. They’ll offer you $110 for a bill worth $500. Honestly, they have to make a profit, but you’re the one losing out.
Instead, look at specialized auction houses. Heritage Auctions or Stack’s Bowers are the big players for high-end notes. If it's a "smaller" find—maybe a star note worth $150—eBay is your best bet. Just make sure to take high-resolution photos. People want to see the corners. They want to see the "centering" of the margins.
Another option is a local coin shop, but be careful. Some specialize in coins and don't know much about "rag" (paper money). You want someone who belongs to the American Numismatic Association (ANA).
The reality of the market right now
The market for paper money is weird. It’s cyclical. Right now, there’s a lot of interest in "Modern Errors." People are obsessed with the Series 2013 B-star notes because of a massive printing overlap between the DC and Fort Worth facilities. If you have two notes with the exact same serial number (which shouldn't happen), you’re looking at a five-figure payday.
But be realistic. Most $100 bills are just $100. You could search through $10,000 worth of cash and find maybe one or two things worth an extra five bucks. It’s a hobby of patience.
However, the hundred dollar bill value is also tied to inflation. A hundred bucks doesn't buy what it used to in 1990. This makes the older, rarer bills even more attractive as a "store of value." Unlike stocks, you can actually hold a rare 1928 Gold Certificate in your hand. There’s a tangible sense of security in that.
Practical steps to take if you find a "weird" bill:
- Do not clean it. Never iron a bill to get wrinkles out. Never use tape. Never use chemicals. You will destroy the value instantly. Collectors hate "processed" notes.
- Put it in a sleeve. Go to a hobby shop and buy a PVC-free plastic currency sleeve. This protects it from the oils on your skin.
- Check the "Print Run." Use a website like MyCurrencyCollection to look up star note run sizes. If the "run size" is 640,000 or less, it’s a keeper.
- Compare sold listings. Don't look at what people are asking for on eBay. Look at "Sold" listings. People can ask $5,000 for a regular bill, but that doesn't mean it's worth it.
- Consider grading. If you think the bill is worth more than $500, pay the $40 to have it professionally graded by PMG or PCGS. A graded bill is much easier to sell because the buyer doesn't have to guess the condition.
The next time you're at the bank or getting cash for a big purchase, take five seconds to look at the serial numbers. You aren't just looking for money; you're looking for a needle in a haystack that might pay for your next vacation. Even if it's just a slightly rare star note, it's a fun way to engage with the history of American finance. Most people just see Ben Franklin. You should start seeing the details that everyone else misses.
