You’ve got one in your pocket right now. Probably crumpled. Maybe it’s got a "Where's George?" stamp on it or some scribbled phone number from a night you’d rather forget. Most of us don’t even look at the United States one-dollar bill anymore. It’s just "a buck." But if you actually stop and stare at that green piece of paper—which, honestly, is mostly cotton and linen anyway—it’s a weirdly mystical, stubbornly old-school object that refuses to change while every other piece of American currency has gone through a neon-colored makeover.
It's a survivor.
While the $20, $50, and $100 bills have been redesigned with giant heads, color-shifting ink, and 3D security ribbons to stop high-tech counterfeiters, the single remains stuck in 1963. That was the last time the design saw a major structural shift. Since then? Nothing. The Secret Service doesn’t really care if people counterfeit singles because it costs more to fake a good one than the bill is actually worth. So, George Washington just sits there, staring out from his oval, surrounded by Latin phrases and Masonic-looking symbols that have fueled more conspiracy theories than the moon landing.
Why the United States one-dollar bill is basically unchangeable
There is actually a law about this. Seriously. Since 2015, Congress has repeatedly inserted a provision into the annual "Financial Services and General Government Appropriations Act" that specifically prohibits the Department of the Treasury from spending any money to redesign the $1 note.
Why?
Vending machines. It sounds ridiculous, but the lobby for the vending machine industry and the people who make those automated bill changers is incredibly powerful. Every time you change the look of a bill, companies have to spend millions of dollars recalibrating sensors and software. Plus, there’s the "blind and visually impaired" factor. The $1 bill is the baseline for the entire system of US currency size.
A lot of people think the "Great Seal" on the back is some secret map to a treasure. It’s not. But the history of how those symbols got there is almost as strange.
Benjamin Franklin, John Adams, and Thomas Jefferson were the original "design committee." They spent weeks arguing about what should represent the new nation. Franklin famously wanted a turkey. He lost. We ended up with an eagle holding 13 arrows and an olive branch. If you look closely at the eagle's head, there’s a constellation of 13 stars. Everything on that bill is obsessed with the number 13. Thirteen stripes on the shield. Thirteen steps on the pyramid. Thirteen leaves on the olive branch.

The Mystery of the Unfinished Pyramid
On the left side of the back of the United States one-dollar bill, you see a pyramid that isn't finished. It has 1776 in Roman numerals at the base (MDCCLXXVI). The top is missing, replaced by the "Eye of Providence" inside a triangle.
The pyramid is meant to represent strength and duration. The fact that it’s unfinished suggests that the United States is a work in progress—a "Novus Ordo Seclorum" (New Order of the Ages). People freak out about the eye, but back in the 18th century, that was a standard Christian symbol for God watching over the nation. It wasn't until way later that pop culture decided it was a sign of a secret world government.
Honestly, the most interesting thing about the back of the bill isn't the symbols; it's the color. We call them "greenbacks," a term that dates back to the Civil War. The government used green ink because it was harder to counterfeit with the photography technology of the 1860s. It also happens to be a color associated with stability and growth.
The $1 Bill vs. The $1 Coin: The War That Never Ends
Every few years, someone in Washington D.C. suggests we kill the United States one-dollar bill and replace it with a coin. The Government Accountability Office (GAO) has released report after report saying the government would save hundreds of millions—sometimes billions—of dollars over several decades if we just switched to coins.
Coins last for 30 or 40 years. A paper dollar lasts about 6.6 years on average before it's so torn and filthy that the Federal Reserve has to shred it.
But Americans hate dollar coins. We’ve tried the Susan B. Anthony. We tried the Sacagawea. We tried the Presidential series. They all end up sitting in jars or at the bottom of cup holders. We like the "foldability" of paper. We like that it doesn't weigh down our pockets. And let’s be real—the "Save the $1 Bill" lobby is basically the paper industry versus the mining industry. It’s a classic American bureaucratic stalemate.

How to tell if your dollar is actually "special"
Not every United States one-dollar bill is worth just 100 cents. Collectors, or "notaphilists," spend their lives looking for specific serial numbers.
Look at the green numbers on the right side of the bill.
- Low Serial Numbers: If you find a bill where the serial number is something like 00000005, that’s worth hundreds of dollars.
- Star Notes: See a little star (*) at the end of the serial number? That means the original bill was damaged during printing and the Bureau of Engraving and Printing (BEP) issued a replacement. These are slightly rarer and can carry a premium.
- Binary Notes: These are bills where the serial number only consists of two digits, like 10100110.
- Ladders: A serial number that goes 12345678. These are the "Holy Grail" for casual collectors.
There is also the "Web Note." In the late 80s and early 90s, the BEP experimented with a different printing process called a web press, which printed on a continuous roll of paper instead of sheets. They only did this for the $1 bill. You can tell if you have one by looking at the small numbers on the face. If there’s only a number and no letter near the bottom right, you might have a web note. They can be worth $10 to $500 depending on the condition.
The Physicality of the Buck
The "paper" isn't paper. It’s a blend of 75% cotton and 25% linen. That’s why it doesn't fall apart when you accidentally leave it in your jeans and run them through the wash. If you look really closely—like, use a magnifying glass—you’ll see tiny red and blue silk fibers embedded in the paper. These are a security feature.
The ink is also special. It’s magnetic.
Vending machines use magnetic sensors to "read" the bill. The ink on the front is different from the ink on the back. The process used is called "intaglio" printing. The paper is forced into the recessed lines of the engraved plate under tons of pressure. This gives the bill that slightly raised, sandpaper-like texture. If you rub a crisp new dollar bill on a white piece of paper, it will leave a green smear. That’s not because it’s fake; it’s because the ink never truly "dries" in the way we think of house paint drying. It’s more like a very thick, permanent paste.
The Federal Reserve Symbols
On the left side of Washington’s face, there’s a black seal. This tells you which of the 12 Federal Reserve Banks actually issued the money.

- C = Philadelphia
- D = Cleveland
- E = Richmond
- F = Atlanta
- G = Chicago

- I = Minneapolis
- J = Kansas City
- K = Dallas
- L = San Francisco
If you have a bill with an "L," it traveled all the way from the West Coast. There’s something kinda cool about tracking the journey of a physical object like that in an era where most of our money is just digital bits moving between servers.
Future of the Buck
Will the United States one-dollar bill ever get a facelift?
Probably not anytime soon. The Treasury is currently focused on redesigning the $20 (to add Harriet Tubman), the $10, and the $5. These redesigns are focused on security. The $1 bill is the least counterfeited note in the world relative to its volume, simply because the ROI for a criminal is so low.
However, there is pressure to change the currency to help the blind. Currently, all US bills are the exact same size and texture, which is a nightmare for accessibility. Most other countries use different sizes or tactile bumps. The US has resisted this for the $1 bill because it would require a total overhaul of every ATM and vending machine in the country.
Practical Steps for Your Wallet
If you want to make the most of the cash you have, or if you’re interested in the "hidden" side of the United States one-dollar bill, here is what you should actually do:
- Check for "Star Notes": Look at the end of your serial numbers. If there's a star, set it aside. Check a site like MyCurrencyCollection to see if that specific run was a "rare" one.
- Inspect Your Change: Look for "Fancy Serials." A "radar" note (reads the same forward and backward) can easily sell on eBay for $20-$50.
- Use the "Where's George?" Website: If you find a bill with a stamp on it, enter the serial number. It’s a fun, low-tech way to see how far your dollar has traveled. Some bills have been logged in all 50 states over 10 years.
- Don't Iron Your Money: People think ironing "crisps" a bill. It actually damages the cotton fibers and can make the magnetic ink harder for machines to read. If a bill is too dirty, the Fed will eventually replace it anyway.
- Acknowledge the $2 Bill: While we're talking about singles, remember the $2 bill is still in circulation. It’s not "rare" or "discontinued." You can go to almost any bank and ask for a stack of them. They are the same size and use the same technology as the United States one-dollar bill, but people hoard them because they think they’re worth more. They aren’t. They’re just two dollars.
The dollar bill is a relic, a piece of art, and a political football all rolled into one. It’s the most recognizable piece of paper on the planet. Even in a world of Apple Pay and Bitcoin, the greenback isn't going anywhere. It’s too baked into the American identity. Next time you pay for a coffee with one, take a second to look at that unfinished pyramid and the tiny "F" for Atlanta. It’s a lot of history for just one hundred cents.
