The $2 bill is real and still legal

Image: Alicia Razuri

Yep, that mysterious $2 bill featuring Thomas Jefferson isn’t a collector’s fantasy. It’s still produced today (though rarely), and the reverse shows the Signing of the Declaration of Independence. People tend to save them, thinking they’re rare, but you can spend them just like any other bill.

The penny used to be made of pure copper

Image: Adam Nir

During WWII, copper was needed for ammo, so in 1943, pennies were made from steel and coated in zinc. They looked silver and rusted easily, some even stuck to magnets! Today, most pennies are actually 97.5% zinc with just a thin copper coating.

George Washington didn’t appear on the first $1 bill.

Image: Jonathan Borba

The very first $1 bill (from 1862) featured Salmon P. Chase, the Secretary of the Treasury at the time. Washington didn't show up until 1869, and Chase had a not-so-humble role in placing his own face there.

There’s a tiny owl hidden on the $1 bill

Image: rc.xyz NFT gallery

Take a magnifying glass to the upper-right corner of the "1" on a dollar bill. Some people swear there’s a tiny owl or spider hidden in the pattern, said to symbolize wisdom or surveillance. Officially, it's just part of the ornate design, but still a fun little mystery!

5

The $100,000 bill actually existed

Image: Dmytro Glazunov

No, you can’t use it at Target. Printed in 1934 and featuring Woodrow Wilson, this gold certificate was used only for transactions between Federal Reserve Banks. It was never meant for public use, and owning one today is illegal!

Lincoln faces the other way for a reason

Image: JustStartInvesting

On most bills, presidents face to the right. But on the penny, Lincoln faces left. One theory is that the designer used a portrait that happened to face left, but it also makes Lincoln the only president looking "inward" when coins are lined up in value order.

"In God We Trust" wasn’t always on our money

Image: Jonathan Borba

That phrase didn’t become mandatory on U.S. currency until 1955 during the Cold War. It first appeared on coins in 1864, but the push to include it everywhere came as a nod to America’s spiritual identity in contrast to atheistic communism.

Coins last way longer than bills

Image: Barry A

Your average dollar bill survives about 6.6 years in circulation. Coins? They can keep going for 30 years or more! That’s why coins are still a budget-friendly way for the government to make money — and we mean that literally!

The buildings on the back aren’t random

Image: Ryan Quintal

Each bill’s reverse side typically features a building related to the person on the front. For instance, the Lincoln Memorial is on the back of the $5 bill (with Lincoln on the front), and the White House appears behind Andrew Jackson on the $20 bill. The choice of course had to do with government history itself! Which building do you think is missing?

10

There are secret codes on every bill

Image: Andrew Dawes

Look closely and you’ll spot tiny letters and numbers that identify which printing plate was used and where the bill was made. Ever see a tiny "F6" on a $1? That means it was printed in Atlanta, Georgia.

11

A dollar is technically made of cloth

Image: Live Richer

Despite calling it "paper money," U.S. bills are actually made of 75% cotton and 25% linen. That’s why they feel so distinct, and don’t shred like regular paper when they get wet (though they still don’t love laundry day).

Los Angeles, California

Image: Venti Views

The Spanish settlers who arrived in the area in the 18th century originally named it El Pueblo de Nuestra Señora la Reina de los Ángeles , which translates to "The Town of Our Lady the Queen of the Angels." Elegant, but kind of a mouthful for a town name! Over time, the Spanish name stuck, but it was shortened to the more practical "Los Angeles." The city officially adopted this name when it was incorporated in 1850, the same year California became a state.

2

New York City, New York

Image: Colton Duke

Before becoming the one and only New York we know today, the city went by a different name. In the 17th century, the Dutch settlers who arrived in the area called it New Amsterdam . However, when the English seized control in 1664, they renamed it New York in honor of the Duke of York.

3

Seattle, Washington

Image: Michael Discenza

Seattle is more than its iconic Space Needle; it has a long history that shaped the city we know today. When European settlers arrived in the area in 1851, they named their settlement New York and added the Chinook word Alki , meaning "by and by," "someday," or "later," suggesting it would one day become as big as New York City. However, in 1852, they changed the settlement’s name to Seattle in honor of Chief Sealth, a Duwamish and Suquamish leader.

Portland, Oregon

Image: Zack Spear

Early settlers referred to the area as The Clearing because it stood out from the dense forests typical of the Pacific Northwest. But in 1845, an event occurred that would change everything. Portland’s two founders, Asa Lovejoy from Boston, Massachusetts, and Francis W. Pettygrove from Portland , Maine, each wanted to name the new settlement after their hometown. So how did they decide? Simple: they flipped a coin . Of course, you know who won!

5

Kansas City, Missouri

Image: Farhodjon Chinberdiev

Kansas City was originally founded as the Town of Kansas in 1850, named for its location near the Kansas River. As it quickly grew, it was reincorporated just three years later as the City of Kansas . Finally, in 1889, it officially became Kansas City.

Fun fact: Kansas City, Missouri, was actually founded before the state of Kansas!

6

Charleston, South Carolina

Image: Tyrone Sanders

Before it became the city we know today, Charleston had another name, though not so different. When it was first settled in 1670, the English named it Charles Town in honor of King Charles II. However, over time, the name gradually evolved in pronunciation to Charleston. In 1783, after the Revolutionary War, the city was officially renamed Charleston.

San Diego, California

Image: Sean Mullowney

San Diego was the first site on the US West Coast settled by Europeans, which is why it's often called "the Birthplace of California." When Spanish explorers arrived in the area in 1542, they named the bay after a different saint: San Miguel . But years later, in 1602, explorer Sebastián Vizcaíno renamed it San Diego, in honor of San Diego de Alcalá (Saint Didacus of Alcalá).

8

Orlando, Florida

Image: Aditya Vyas

In 1840, the first settlers arrived in what we know today as Orlando. They were the Jernigan family, who named the place after themselves. A post office with that name was even established in 1850. However, about 6 years later, Jernigan officially changed to Orlando. Although the exact reason isn't entirely clear, there are several theories. A popular one claims it was named after Orlando Reeves, a soldier who may have died in the area during the Seminole Wars. Another well-known theory suggests the name came from Orlando , a character in Shakespeare’s As You Like It .

9

Cincinnati, Ohio

Image: Matt Koffel

In the 1780s, the first settlement in this area was called Losantiville , a name created from a mix of words meaning "The town opposite the mouth of the Licking River." But in 1790, the first governor of the Northwest Territory, who was also a member of the Society of the Cincinnati (named in honor of the Roman general Lucius Quinctius Cincinnatus), disliked Losantiville and decided to change it to its present name.

10

Atlanta, Georgia

Image: Christopher Alvarenga

Atlanta didn't just have one or two names; it had three! By the mid-19th century, the area where the city stands today had become a transportation hub where several railroad lines converged. Because of this, in 1837, the area was called Terminus , meaning "the end of the line." Then, in 1843, the name was changed to Marthasville , in honor of Martha, the daughter of Georgia Governor Wilson Lumpkin. Finally, just two years later, the city was renamed Atlanta. This name is believed to be a shortened form of "Atlantic," referring to the Western and Atlantic Railroad.
