Money Materials

Image: Jorge Salvador

We call them paper bills, but do they undergo the same process as any other paper? Naturally, they don’t. U.S. bills are mainly made of two materials: 75% of their composition is cotton and the 25% left is linen. Besides, they have randomly disbursed red and blue security fibers embedded in the paper.

This special blend is made by only one company in America and that is Crane & Co . The company, based in Massachusetts patented this special blend and it has been the sole provider of paper for currency since 1879.

Origin of the U.S. dollar symbol

Image: Paris Bilal

The dollar sign is a matter of debate. One line or two across a capital S, the symbol is today a worldwide sign for money, but where does it come from?

Even if there are several theories as to where the U.S. dollar symbol comes from, all of them agree that it was derived from the Spanish peso . When the time came, and the new nation needed its own currency, the basis was that of the Spanish coinage, which was the most common currency in the colonies before the country’s independence.

The adoption of the sign was made official in 1785, and today, the United States is not the only country that uses this symbol, Canada, Australia, and New Zealand do too!

Who appears on the bills?

Image: AR

Having your face forever stamped on the little piece of paper that rules the world should be a milestone in your career, right? However, there were certain rules as to who qualifies to be granted this honor .

Probably, the most surprising, yet the most logical one is that no living person can be portrayed in American currency. Since the Founding Fathers considered it unpatriotic to be portrayed while alive, this was first a tradition and then made official in an Act of Congress in 1866 .

However, contrary to popular belief, this honor is not only reserved for presidents! Anyone who contributes to the nation can be portrayed.

Folding Papers

Image: Emilio Takas

Bills come and go all the time. We take them out of our pockets and put them in our purses only to take them out again a few hours later and give them to the shop assistant. For a life that busy, we can only hope the paper is tough enough , right?

Well, as a matter of fact, it is. Compared to regular paper, which can only be folded 400 times before it breaks, money paper can be folded up to 8,000 times before it breaks .

It's not that you’re going to try it out and see, but you can rest assured: Fold your bills away, they can handle it!

Damaged Goods

Even if they can be folded that many times, the life of bills is limited, not to mention accidents happen. Who hasn’t sent a bill to the washing machine by chance?

So, what happens when a bill is damaged? Well, at least 50% of it has to be clearly identifiable for the bank to replace it , otherwise, you’ll just lose your money. You don’t feel like folding them much now, right?

On the other hand, and mainly due to time damage, at least 70% of the new bills are used to replace old bills . These bills, once taken out of circulation are shredded and sent to companies that can recycle them!

Security Features

Counterfeiting has been a problem ever since paper money was created and statistics about which countries counterfeited most of the money are simply shocking. But we won’t get into that.

What we will say is that thanks to technological advancement, the U.S. bill is getting harder and harder to counterfeit. In modern bills, there are at least six security features which are: UV security ribbon, raised printing, microprinting, 3D security ribbon, color-shifting ink, and traditional watermarks. Do you pay attention to them?

U.S. Coins

Image: Kenny Eliason

Coin production in America is in charge of the U.S. Mint and there are four production facilities across the country. They are located in Philadelphia, Denver, San Francisco, and West Point.

It is estimated that every year the Mint produces about 16 trillion coins which are valued at over $1.09 billion dollars. What is truly impressive is that Americans throw away an estimated 62 million dollars worth of coins every day!

They may not be worth much alone but don’t throw them away, all of them together can make you rich!

Green Ink

Image: maria pagan

Have you ever wondered why the U.S. dollar bills were green? It is not about design or aesthetics, even if we think they look pretty.

The decision to use green ink was a matter of security, in order to prevent counterfeiting. Back then, black and white ink made it easier to create photographic fakes. For that reason, green was the color of choice, and, when paper money was standardized in 1929, it had great acceptance due to the positive connotations of the color . Do you like it?

Andrew Jackson’s Take on Paper Money

Image: Elsa Olofsson

Every denomination has an important figure stamped on the front. In the case of the 20-dollar bill, Andrew Jackson was the chosen one.

Jackson was the seventh president of the United States and, even if it is not a rule that only presidents can be portrayed, his contributions gained him this honor.

Ironically, Jackson was not in favor of using paper money. For him, only gold and silver coins should have remained legal tender. After learning this, one can only assume he wouldn’t be so happy to be the face of the 20-dollar bill, right?

Facelifts and redesigns

Image: Kenny Eliason

One of the ways of keeping paper money safe and hard to counterfeit is by giving the bills new designs.

New faces were expected to appear in future bills, but, in the meantime, the changes always had to do with the proportions of the elements within each denomination. Bigger faces, rearrangement of the signatures, stuff like that.

Now, these changes and facelifts haven’t reached all the bills. 1-dollar bills haven’t been changed or redesigned ever since 1929. Why is that? Because it is not worth the trouble for criminals to counterfeit. One dollar won’t take them too far!

Cattails

Image: Vlad Tchompalov

If you’ve ever seen a cattail and thought it looked kind of yummy, you were on the right track! Cattails grow abundantly in marshy areas across the U.S., and nearly every part of this plant is edible. Often called the "supermarket of the swamp," cattails are incredibly rich in carbohydrates and are a highly versatile food source. These plants not only provide nutrition but also materials for shelter and fire-starting, making them a top resource for wilderness survival in America.

The roots, once cleaned and cooked, have a potato-like quality and can also be dried and ground into flour. Impressively, they even outperform potatoes in starch yield per acre. Young shoots are edible as well, offering a fresh bite when raw or a tender taste when boiled, much like asparagus.

Dandelions

Image: Keegan Houser

Often dismissed as a pesky weed, dandelions are actually among the most nutritious plants you can find in the wild. In fact, dandelions are considered even more nutritious than broccoli or cabbage! Every part of the dandelion is edible, from the leaves to the roots. With a taste and texture similar to chicory, the leaves are packed with vitamins A and C and be eaten raw in salads or cooked like spinach.

The bright yellow flowers can also be used to make tea, while the roots can be roasted as a coffee substitute. Dandelion tea is loaded with powerful antioxidants, including beta-carotene and polyphenols, and studies suggest it may benefit heart health.

Wild Asparagus

Who knew you could harvest your own asparagus in the wild? Wild asparagus grows across much of the U.S., particularly in moist, sunny areas. While it looks similar to its cultivated cousin, wild asparagus tends to be thinner and tougher. When foraging, look for young shoots, which are more tender and can be eaten raw or cooked.

Like its commercial counterpart, wild asparagus is high in fiber and vitamins, offering a nutritious snack or even a potential side dish in a survival situation.

4

Acorns

Image: Annie Spratt

You’re likely already familiar with acorns, the nuts of oak trees. Found abundantly across the U.S., particularly in forests and woodlands, these wild nuts are indeed edible after some processing. Acorns contain bitter tannins, which can be toxic and need to be removed by repeated boiling or soaking in water.

Once safe to eat, acorns can be either roasted or ground into flour. Though they don’t taste like much, they’re packed with carbohydrates, fats, and proteins. Historically, acorns were a staple food for Native Americans and ancient cultures worldwide, proving their value as a survival resource.

5

Cactus (Prickly Pear)

Image: George Pagan III

In the arid landscapes of the American Southwest, prickly pear cacti offer both nourishment and hydration. The pads (nopales) and the fruit (tunas) are not only edible but are also staples in Mexican cuisine.

The cactus fruit, known as a prickly pear, is super sweet and can be eaten raw right off the plant. Depending on ripeness, the flavor ranges from mildly sweet to syrupy. Packed with vitamin C and water, prickly pear cacti can be a true lifesaver if you find yourself stranded in the desert.

6

Wild Onions

Image: Zoe Schaeffer

Wild onions grow widely across the U.S., thriving in fields, forests, and even backyards. Their bulbs, stems, and leaves are all edible and can be used just like store-bought onions to add flavor and nutrition to any meal. But foragers, beware—there’s an important distinction to keep in mind!

A highly toxic lookalike called death camas can be easily mistaken for wild onions, and as its name kindly suggests, it can have potentially lethal effects if consumed. The easiest way to tell them apart? Wild onions have a strong onion scent, while death camas has no odor. When in doubt, always trust your nose. That being said, unless you are 100% confident in your ability to identify wild onions, it’s wise to consult an expert or avoid foraging them altogether.

Pine Nuts

Pine trees are scattered across America, and their seeds—pine nuts—are a nutritional powerhouse. These small seeds, found inside pine cones, are rich in fats and proteins, making them a concentrated source of energy. In fact, pine nuts have sustained Native American tribes for centuries.

While they are labor-intensive to harvest, the effort is worthwhile. Packed with calories and bursting with flavor, they are an abundant and reliable food source. But it doesn't end there—surprisingly, most parts of a pine tree can be consumed, including the bark, needles, cones, and resin, either as food or for medicinal purposes.

8

Chicory

Image: Christopher Luther

Chicory is often found along roadsides and in open fields throughout the U.S. The plant is recognizable by its bright blue flowers, and while its leaves can be eaten like lettuce, its roots are also useful—they can be roasted and used as a coffee substitute.

During the American Civil War, soldiers used chicory to stretch their coffee supplies, and even today some beer brewers occasionally use roasted chicory to add a bitter flavor to stout varieties.

9

Blackberries

Who hasn't enjoyed picking a few blackberries during a walk? Blackberry bushes thrive across the country, especially in sunny, open areas. These delicious berries are loaded with vitamins C and K, along with fiber, making them an excellent survival food when in season. Additionally, their leaves can be brewed into a soothing tea.

Wild raspberries and strawberries are similarly plentiful in the American backcountry. Their unmistakable appearance and sweet flavor make them a great choice for novice or inexperienced foragers to safely enjoy nature’s pantry.

10

Clover

Who knew that stumbling upon a clover patch could bring more than just good luck? Clover grows abundantly across the U.S., from lawns to meadows, and both its leaves and flowers are edible. The flowers are often dried to make tea, while the leaves can be tossed directly into salads or soups an added nutritional boost.

Rich in protein and minerals, clover has historically served as fodder for livestock, but it can also provide essential nutrition for humans, especially in a survival situation! Its versatility certainly makes it a valuable addition to any forager's repertoire.

Best known for her 1930s–40s film career, Hollywood icon Hedy Lamarr also co-invented frequency-hopping spread spectrum technology to prevent enemy jamming in WWII. And if you think it’s no big deal, know it’s the basis for modern Bluetooth and Wi-Fi!

While largely overlooked as an inventor at her time, she was posthumously inducted into the National Inventors Hall of Fame in 2014.

Sybil Ludington

Image: Taylor Brandon

According to many historians, at just 16 years old, Sybil Ludington rode about 40 miles through the night in 1777 to alert American militia of a British attack on Danbury, Connecticut.

This would make her ride roughly twice as long as Paul Revere’s . While some scholars question the veracity of her story, a statue stands in her honor in Putnam County, New York.

Born into slavery in 1838, Reeves became one of the first Black U.S. Deputy Marshals west of the Mississippi. He made over 3,000 arrests during his law enforcement career.

Many historians believe his exploits may have inspired the Lone Ranger character, although his name rarely appears in history textbooks.

Mary Edwards Walker

Image: David Trinks

A Civil War surgeon and suffragist, Walker treated soldiers on the front lines and was even captured as a prisoner of war.

In 1865, she became the first woman to ever receive the Medal of Honor. Her unorthodox dress style and fearless activism made her a striking figure in 19th-century America.

5

Clara Barton

Known as the "Angel of the Battlefield," Barton provided medical care during the Civil War and later founded the American Red Cross in 1881.

Though once a household name, her legacy has faded compared to other, more widely remembered wartime figures.

A college professor turned Union colonel, Chamberlain famously held Little Round Top during the Battle of Gettysburg, a pivotal moment in the Civil War.

He was awarded the Medal of Honor and later became governor of Maine, but his unexpected battlefield brilliance is often overlooked in Civil War discussions.

In 1862, Smalls, a formerly enslaved sailor, seized a Confederate ship and delivered it to Union forces, securing freedom for himself and his crew.

He later served five terms in Congress, advocating for Black education and civil rights.

Known as the "Father of the FDA," Harvey Wiley was a chief chemist in the late 1800s whose "Poison Squad" tested various food additives, leading to the 1906 Pure Food and Drug Act.

This law laid the foundation for the FDA and led to the removal of many dangerous substances from consumer products. Notably, it prompted Coca-Cola to eliminate cocaine from its formula in the early 20th century.

The last war chief of the Crow Nation, Joe Medicine Crow, completed several traditional war deeds during WWII—including counting coup and stealing enemy horses —and earned both the Bronze Star and the French Légion d’honneur.

Part of his legacy was bridging Native American warrior traditions with modern military service, honoring both cultural heritage and patriotic duty.
