You’ve probably got a crumpled five-dollar bill sitting in your pocket right now. Or maybe a crisp twenty you just pulled from an ATM. We use them constantly, yet we rarely actually look at them. Most people think American dollar bill denominations are pretty straightforward—ones, fives, tens, twenties, and the occasional hundred if it’s a good payday. But the reality of U.S. paper currency is a lot weirder, more historical, and frankly more complex than just "dead presidents on green paper."
Cash is changing.
While everyone talks about Bitcoin or Apple Pay, physical bills still account for a massive chunk of daily transactions, especially for small purchases. But have you ever wondered why we don't have a two-dollar bill in regular rotation? Or why the $500 bill disappeared? The Bureau of Engraving and Printing (BEP) produces billions of notes every year, and each one is a masterpiece of security and history.
The Standard Lineup: What’s Actually in Your Wallet
The Federal Reserve currently issues seven denominations: $1, $2, $5, $10, $20, $50, and $100. That’s it. If someone tries to hand you a $15 bill, you're being pranked or scammed.

The $1 bill is the workhorse. It features George Washington and has stayed largely unchanged since 1963. Why? Because the vending machine lobby is incredibly powerful. Seriously. Every time the government talks about redesigning the $1 or switching to a coin, companies that make vending machines and laundromat equipment point out that it would cost billions to recalibrate their sensors. So, the $1 stays old-school. It doesn't even have a watermark or a security thread.
Then there’s the $2 bill. It’s the "weird" one.
Thomas Jefferson is on the front, and the signing of the Declaration of Independence is on the back. People often think they are rare or worth a fortune. They aren't. You can walk into almost any bank and ask for a stack of them. They represent less than 1% of all notes in circulation, mostly because people hoard them thinking they're special, which keeps them from actually being used at the grocery store.
The Mid-Range Heavy Hitters
Abraham Lincoln sits on the $5 bill. It was recently redesigned to include a giant purple "5" on the back to help people with visual impairments. Then you’ve got Alexander Hamilton on the $10. He’s the only non-president on a current note besides Benjamin Franklin. Fun fact: Hamilton was actually the first Secretary of the Treasury, so it makes sense he’s on the money, even if he never made it to the White House.
The $20 bill is the ATM king. Andrew Jackson is the face of the twenty, though there has been a decade-long saga about replacing him with Harriet Tubman. As of 2026, the Tubman $20 is still in the bureaucratic pipeline, with the Treasury citing security features and "complex production schedules" as the reason for the delay.
High-Denomination Notes: The $500, $1,000, and Beyond
Believe it or not, the U.S. used to print much bigger bills.
We’re talking $500, $1,000, $5,000, and $10,000 notes. There was even a $100,000 gold certificate used exclusively for transactions between Federal Reserve banks. You couldn't just walk into a bakery and buy a croissant with a $100,000 bill.
The $500 bill featured William McKinley. The $1,000 had Grover Cleveland. These were officially discontinued in 1969. Why? Primarily to fight organized crime. It’s a lot harder to smuggle a million dollars in twenties than it is in $5,000 bills. If you find one of these today, it is still legal tender. You could spend a $500 bill at a gas station, but that would be a terrible mistake. Because of their rarity, they usually sell to collectors for three or four times their face value.
Why the $100 Bill is Different
Benjamin Franklin is the star of the $100 bill, the highest denomination currently being printed. It is the most frequent target of counterfeiters outside the U.S. Because of this, it’s the most high-tech piece of paper you own. It has a 3D Security Ribbon that isn't printed on the paper—it’s woven through it. When you tilt the bill, the bells change to 100s.
It’s honestly kind of a marvel of engineering.
Security Features You Should Actually Check
Counterfeiting is a real problem, even with smaller american dollar bill denominations. You don't need a fancy UV light to check your cash. Most people just look for the watermark, but you should also look for the "color-shifting ink." On any bill from $10 and up, the number in the bottom right corner shifts from copper to green when you tilt it.
Also, feel the paper. Federal Reserve notes are 75% cotton and 25% linen. They aren't actually paper at all; they’re fabric. That’s why they don't fall apart in the washing machine like a receipt does. If a bill feels "waxy" or like standard printer paper, it’s a fake.
The Future of Physical Cash
Is paper money dying?
Not really. While digital payments are skyrocketing, the amount of physical currency in circulation actually grows most years. People like the privacy of cash. They like the tangibility. The Federal Reserve continues to invest billions into the next generation of notes. We can expect a full "family" of new designs over the next decade, starting with the $10, then the $50, and eventually the $20 and $5.
The $1 and $2 will likely be the last to change, if they ever do.
Practical Tips for Handling Different Denominations
If you’re traveling or just trying to be smarter with your money, here is the "pro" way to handle U.S. currency:
- Avoid $50s and $100s for daily errands. Many small businesses won't accept them because they don't keep enough change in the till or they fear counterfeits.
- Request $2 bills at the bank for tipping. It’s a small thing, but it’s memorable. Bartenders and servers usually get a kick out of them, and it makes you stand out.
- Check your "star notes." Look at the serial number. If there is a small star (*) at the end, it means the bill was a replacement for a misprinted one. Some collectors pay a premium for these.
- Don't tape torn bills. If you have a bill that is ripped, as long as 51% of it is intact and the serial numbers are visible, you can take it to a bank and they will swap it for a fresh one. If it’s really mangled, you have to mail it to the Bureau of Engraving and Printing’s Mutilated Currency Division.
Basically, the cash in your wallet is a blend of 18th-century tradition and 21st-century anti-counterfeiting tech. Next time you pay for a coffee, take a second to actually look at the ink and the watermarks. It’s a lot more interesting than a digital number on a screen.
Actionable Next Steps:
- Audit your wallet: Check the bottom right corner of your $10s, $20s, or $50s. Tilt them to see if the ink actually shifts color. If it doesn't, you might have a counterfeit.
- Visit a local bank: Ask for five $2 bills. Keep them for tips or small gifts. It's a great way to see a "rare" denomination in person without spending more than face value.
- Search for Star Notes: Look at the serial numbers on your cash. If you find a star at the end, look up its rarity on a site like MyCurrencyCollection. You might be holding something worth more than its face value.
