Ever stared at a twenty-dollar bill and wondered if it’s actually real? You’re not alone. Honestly, it’s the most commonly faked note in the U.S. domestic market. While we all know the general "greenish" look and Andrew Jackson’s face, there’s a whole world of hidden ink, plastic threads, and tiny symbols that most of us completely ignore while standing in a checkout line.
Basically, if you’re just looking for Jackson’s hair and the number 20, you’re doing it wrong. Modern currency is a high-tech sandwich of cotton and linen, designed to break a counterfeiter’s heart.
The Face of the Bill: More Than Just Jackson
If you’re looking at the front of a standard $20 bill (specifically the Series 2004 and later), the first thing you’ll notice is the color. It isn’t just green anymore. There’s a distinct peach and blue wash in the background. It’s subtle, but it’s there to make it harder for someone with a basic home printer to get the "vibe" right.
President Andrew Jackson is still the star of the show, but he’s "broken out" of his traditional oval. His shoulders now bleed into the border of the note. To his left, there’s a large, blue eagle. To his right, there’s a smaller, metallic green eagle. These "Symbols of Freedom" aren't just for decoration—they use a special intaglio printing process. If you run your fingernail over Jackson’s vest or the words "THE UNITED STATES OF AMERICA," it should feel scratchy or raised. If it’s smooth as a baby’s forehead, you’ve got a problem.
What Does a 20 Bill Look Like Under Modern Scrutiny?
Let’s talk about the stuff you can’t see at a glance. Counterfeiters have gotten pretty good at mimicking the "look," but they usually fail at the "physics."
The Color-Shifting Ink
In the bottom right corner, you’ll see a big "20." Tilt the bill back and forth. It should shift from a distinct copper color to a forest green. It doesn’t just "sparkle"—it actually changes hue. This is one of the hardest things to fake because the ink itself is extremely expensive and restricted.
The Ghost in the Paper
Hold that bill up to a light. To the right of Jackson’s main portrait, in the blank white space, a second Jackson should appear. This is the watermark. It’s not printed on the paper; it’s in the paper. It should be visible from both sides. If you see a watermark of Abraham Lincoln on a $20 bill, someone "bleached" a $5 bill and printed a $20 over it. It happens more often than you'd think.
The Glowing Thread
There is a vertical plastic strip embedded to the left of the portrait. If you hold it to the light, you can read "USA TWENTY" and see a tiny flag. But here’s the kicker: if you put it under a UV (ultraviolet) light, that thread should glow a bright, neon green. It’s a fast way for bartenders and cashiers to check a stack of bills without squinting.
The Secret Numbers on the Back
Flip the bill over. You see the White House, obviously. But look at the blank space around it. You’ll see tiny, yellow "20s" scattered like confetti. This is part of the EURion Constellation.

Modern scanners and photo-editing software (like Photoshop) are actually programmed to recognize this specific pattern of tiny numbers. If you try to scan a $20 bill, most modern software will literally stop you or refuse to print it. It’s a "digital booby trap" that most people never even notice.
Why the $20 Bill is Changing (Eventually)
You might have heard the buzz about Harriet Tubman. Back in 2016, the Treasury announced she would eventually replace Jackson on the front of the bill. While the redesign has been delayed multiple times due to political shifts and technical hurdles, the Bureau of Engraving and Printing is still working on it.
Current timelines suggest a new design might not hit our wallets until closer to 2030. For now, Jackson remains. But even when the face changes, the security tech—like the color-shifting ink and the security thread—will likely stay the same or get even more futuristic.
How to Handle a "Funny" Bill
So, what if you find a bill that feels off? Maybe the lines are blurry, or the "20" doesn't shift color.
- Don't put it back in your wallet. Passing a counterfeit bill is technically a crime, even if you didn't make it.
- Compare it. Put it next to a bill you know is real. The difference in paper texture is usually the biggest giveaway. Real money isn't really paper; it's 75% cotton and 25% linen. It feels like fabric because, well, it kind of is.
- Check the Serial Numbers. If you have two bills with the exact same serial number, at least one of them is fake.
To stay safe, get in the habit of doing the "Tilt, Light, Feel" check. Tilt for the color shift, hold it to the light for the watermark/thread, and feel for the raised ink. It takes three seconds and can save you from being out twenty bucks.
If you suspect a note is counterfeit, the best move is to contact your local police or the U.S. Secret Service. They're the ones who actually handle the "funny money" beat. Keep the bill, try to remember who gave it to you, and don't try to spend it at the gas station—you don't want to be the one explaining things to a skeptical clerk.
