You’re staring at a crumpled five-dollar bill in the checkout line and something looks... off. Right at the end of the serial number, where a letter should be, there’s a tiny, solid star. It’s not a printing error. It's not a secret signal from a shadow government. Honestly, it’s much simpler than that, though collectors might tell you it’s worth a small fortune if the timing is right.
A star on serial number dollar bill indicates what the Bureau of Engraving and Printing (BEP) calls a "Replacement Note."
Money printing is an industrial process. Things go wrong. Sheets get smeared, ink runs dry, or the paper jams in the high-speed presses. When a sheet of currency is ruined during the manufacturing process, the BEP can't just print another one with the exact same serial number to fill the gap. That would mess up the accounting. Instead, they swap the damaged sheet with a pre-printed "star note." This acts as a placeholder so the total count of bills in a brick remains correct for the Federal Reserve.
The Mechanical Reality of the Star Note
Think about the sheer volume of paper moving through the facilities in Washington, D.C., and Fort Worth. Millions of notes every single day. The BEP uses massive 32-note or 50-note sheets. If just one bill on a 50-note sheet has a flaw—maybe a tiny ink blotch on George Washington’s nose—the entire sheet is usually pulled.
They don't just throw it away and forget it. They destroy it.
To keep the serial number sequences consistent for the banks, they grab a sheet from a separate run. These replacement sheets are printed in advance. Because the serial numbering system is strictly regulated, these backup bills are given their own unique identifier: that famous star. On modern Federal Reserve Notes, the star replaces the suffix letter at the end of the serial number.
It’s basically a "oops, let's try that again" stamp.
Why Some Star Notes Are Worth Way More Than Face Value
Most star notes are just worth a buck. Or five. Or whatever the number in the corner says. You’ve probably spent dozens of them in your lifetime without even noticing. But there’s a subculture of "numismatists"—currency nerds—who track these things like hawks.
The value comes down to one word: Rarity.

When the BEP prints replacement notes, they do them in "runs." A run might be 3,200,000 bills. That’s a lot. If you find a star note from a massive run, it’s probably only worth face value to anyone but a very dedicated beginner. However, sometimes a run is tiny. We’re talking 640,000 notes or even as low as 12,800.
The Rarity Scale
Collectors use a specific logic to determine if your star on serial number dollar bill is a keeper:
- Common Runs: Over 1 million notes. These are the ones you find in your change at 7-Eleven. Keep them if they’re crisp, but don't expect to retire on them.
- Medium Rarity: Between 500,000 and 1,000,000 notes. You might get a few extra dollars over face value on eBay.
- Rare Runs: Under 640,000 notes. This is the sweet spot.
- Ultra-Rare: Runs of 100,000 or fewer. These are the "holy grail" finds in general circulation.
Condition is everything. A rare star note that’s been through a washing machine and has a coffee stain is basically just money. But a rare star note that looks like it just came off the press? That’s where the collectors start sweating.
How to Check Your Bill’s Pedigree
You can't tell how rare a bill is just by looking at the star. You need to know the context of its birth. Specifically, you need to check the Series year (like 2017 or 2021) and the Federal Reserve Bank letter.
There are websites dedicated entirely to this. The most famous is MyCurrencyCollection.com, which hosts a "Star Note Lookup" tool. You plug in the denomination, the series year, and the serial number. It tells you exactly how many were printed in that specific run.
It’s kinda like a DNA test for your wallet.
I once found a 2013 $1 star note. I thought I was rich. I looked it up, and it turned out it was part of a run of 3.2 million. Total value? Exactly one dollar. It was a bit of a letdown, but that's the game.
The Duplicate Serial Number Glitch (The 2013 Project)
If you really want to dive into the deep end, look into the 2013 New York $1 star note mishap. This is one of the biggest blunders in modern printing history.

In 2014 and 2016, the BEP facilities in D.C. and Fort Worth accidentally printed two identical runs of $1 star notes for the New York (B) Federal Reserve Bank. They have the exact same serial numbers.
This shouldn't happen. It’s a violation of the "unique serial number" rule.
There are thousands of pairs of "twin" bills out there. If you find one half of a pair, it's worth a bit. If you manage to find the matching serial number from the other printing facility? You’re looking at thousands of dollars. People are actually using specialized forums to try and "match" their twins with strangers across the country. It's like a national scavenger hunt with high stakes.
Identifying the Symbols
It’s easy to get confused with all the letters and numbers. On a standard $1 bill, you have the serial number. It usually starts with a letter (indicating the series), followed by eight numbers, and ends with a letter (the suffix).
When that suffix letter is replaced by a star, it’s a replacement note.
On older "Large Size" notes from the early 20th century, the star might be at the beginning of the serial number. It all depends on when the bill was made. But for anything you’re pulling out of an ATM today, look at the end of the string.
Misconceptions and Rumors
People love a good conspiracy. I've heard folks claim that star notes are "experimental" money or that they contain tracking chips. They don't.
Others think they are "bank teller" money used to mark the end of a stack. Also not true.

The star is strictly an accounting tool for the BEP. If they print 100,000,000 bills, they need to deliver 100,000,000 bills. If they mess up 500 of them, the star notes fill those 500 slots so the ledger stays balanced. Simple as that.
What to Do If You Find One
So, you’ve found a star on serial number dollar bill. What now?
First, stop yourself before you spend it on a pack of gum. Even a common star note is worth keeping if it’s in "Uncirculated" condition. "Uncirculated" means no folds, no creases, no rounded corners. It looks like it was born yesterday.
- Check the Rarity: Use a lookup tool immediately. If it's a "Rare" run (under 640k), put it in a plastic sleeve.
- Evaluate the Condition: Look for "color" and "crispness." Hold it up to the light. If you see a faint vertical line where it was once folded, the value drops significantly.
- Check for "Fancy" Numbers: Does the star note also have a "fancy" serial number? Like 00000123* or 88888888*? If you have a star note that is also a "solid" or a "ladder," you’ve hit the jackpot.
- Don't Clean It: Never, ever try to iron or wash a bill to make it look better. Collectors can tell, and it ruins the value instantly.
The Future of the Star Note
As we move toward a more digital economy, physical cash is becoming a bit of a relic. Some experts think this will make star notes even more collectible in twenty years. Others think physical money will eventually be phased out entirely, making these little paper "errors" historical artifacts.
The BEP is constantly updating security features—watermarks, color-shifting ink, 3D ribbons. But through all the tech upgrades, the star remains. It's a low-tech solution to a high-speed manufacturing problem.
Next time you get cash back, take a second. Look at the end of that green ink string. That little five-pointed star is a tiny window into the massive, slightly imperfect machine that runs the global economy.
Actionable Next Steps for Curious Collectors
If you're ready to see if you have a hidden gem, follow this sequence.
Pull every bill out of your wallet right now. Sort them by denomination. Look at the end of the serial numbers for that star. If you find one, go to a rarity database and check the "Series" (the year) and the "Serial Number." If the run size is in the "red" or "yellow" zone (typically under 1 million), buy a PVC-free currency sleeve to protect it from the oils on your skin. Even if it's not worth $500 today, it’s a piece of history that’s worth more than the paper it’s printed on.
Check the "B" (New York) 2013 $1 bills especially closely. You might be holding half of a "duplicate" pair that collectors are desperate to reunite. Even a single 2013 B star note in decent shape can fetch a premium because of the notoriety of that specific printing error. Keep your eyes peeled; most people spend their luck without ever realizing it was in their pocket.
