The secrets of the greenback

Dollar bills are green for this reason

Image: Pepi Stojanovski

The U.S. dollar is one of the most powerful and recognizable currencies in the world, but its physical form is unique for many other reasons . From its composition to its symbols, dollar bills and coins are carefully designed to combine history, security, and convenience. Let’s explore our national currency!

1
What are bills made of?

Unlike other currencies, dollar bills are not made of paper or plastic. U.S. dollar bills are made from a special fabric blend composed of 75% cotton and 25% linen. This mix makes the bills extremely durable and resistant, and they can be folded about 4000 times before tearing.

What bills are valid?

Any U.S. dollar bill that was legally printed is valid, no matter how old, as American currency does not have an expiration date. While some bills might not be accepted by businesses of foreign exchange services due to their condition or if they are a discontinued version of the bill, the bills themselves are still valid, and American banks will accept them, though they might take them out of circulation.

American leaders

Five bills have a depiction of an American president. The exceptions are the $10 bill, with Alexander Hamilton on the front, and the $100 bill, with Benjamin Franklin. The $1 bill, depicting George Washington, is extremely symbolic: several elements are repeated 13 times as a nod to the thirteen colonies, and it showcases the Bald Eagle and the Eye of Providence as a sign of God watching over America.

4
A change in size

Did you know that dollar bills used to be so big that they were nicknamed "horse blankets"? Original dollar bills were 7.4 × 3.1 inches. In 1929, the Treasury Department reduced the size of bills to 6.14 × 2.61 inches to reduce production costs and materials. Old bills, though still valid, are worth much more as collector items.

5
Uniformity

Besides their value and design, all dollar bills have the same size (6.14 × 2.61 inches), color, and weight (1 gram) , which sets American currency apart from other countries where bills of different values are differentiated by size, color, or both. Why doesn’t the U.S. implement differences among bills? The cost of adapting vending machines, bank drawers, and ATMs to new bill sizes would cost billions of dollars.

6
Hard to copy

Originally, dollars were not green, but black. As time passed, green ink was favored, as it was cheap and did not fade as much as black. The new color also prevented people from using black-and-white cameras to create counterfeit money. Currently, dollar bills are predominantly green, but newer versions also include extra colors, such as pink, orange, or purple.

A $100,000 bill?

Have you ever seen a $500 or 1,000 dollar bill? What about a $100,000? Up until 1945, the U.S. Treasury printed $500, $1,000, $5,000, $10,000, and $100,000 notes , in addition to the values currently in use. These higher-value notes were mainly intended for bank and government use, but were sought by criminals as they made it easier to hide large amounts of money. Even though they were officially discontinued in 1969, these notes are still valid, though rare, and they have a high worth as collector's items.

8
No numbers

Unlike bills, American coins have different sizes and colors related to their value. Originally, gold, silver, and copper were used for coins, but modern coins are made of copper, zinc, or nickel. Besides their size and design, the value of each coin is printed in letters, not in numbers , alongside depictions of American presidents.

9
Liberty for all (the coins)

Image: Money Knack

By law, all American coins must include six specific details : the word ‘Liberty’, the name of our country, the national motto "In God We Trust", the oldest American motto "E Pluribus Unum", the value of the coin, and the year. Each coin also includes a mint mark that shows where it was made: "P" for Philadelphia, "D" for Denver, "S" for San Francisco, and "W" for West Point.

10
A global currency

Image: Logan Voss

The American dollar is one of the most powerful currencies in the world, acting as a backbone for international trade and finances. It is estimated that two-thirds of the physical dollars in circulation are outside American territory. Besides the U.S. and its territories, eight sovereign nations have the U.S. dollar as their official currency, with several more accepting it as legal tender.

Not your regular celebration

10 American festivals with unusual themes

When it comes to festival themes, one might think of things like wine, beer, cheese, or apple pie. Or maybe, if that sounds boring, huge mushrooms, cryptids, cow manure, and even corpses preserved on ice. America is home to thousands of festivals every year, some of them less common in theme, but certainly more unique. Here are some of them!

1
Gilroy Garlic Festival, California

Image: team voyas

The city of Gilroy, California, is known for being a major garlic producer and is even more known for hosting one of the most important food festivals in America. Originally inspired by a French garlic festival, Gilroy opens their doors to all garlic lovers the last weekend of July, and attracts thousands of visitors every year. Not recommended if you are allergic or just a vampire.

2
Mothman Festival, West Virginia

Mothman is one of the most distinguished cryptids in American folklore and a point of pride for its home turf, Point Pleasant, West Virginia. Since 2002, a festival centered around the figure of Mothman has been celebrated yearly, and has been a big source of tourism for the town.

3
Humongous Fungus Festival, Michigan

In the 1980s, Crystal Falls, Michigan, was the site of a significant discovery: a vast underground colony of Armillaria gallica , commonly known as the honey mushroom. Since 1991, Crystal Falls has celebrated its fungal neighbors with the Humongous Fungus Festival, which includes a parade, a cook-off —mushroom themed, of course—, and many more community events.

4
Surfing Santas, Florida

Florida beaches might not have the ideal Christmas weather, but they are perfect for surfing. This is why, every Christmas Eve, Cocoa Beach, Florida, is the scene of Surfing Santas, a festival where, as the name suggests, people surf dressed as Santa Claus. Initially an open beach party turned festival, the proceeds are destined to local charities and to the Florida Surf Museum.

5
Frozen Dead Guy Days, Colorado

As the name of this certainly peculiar festival indicates, there is a corpse involved. The remains of Bredo Morstøl, originally from Norway, are cryopreserved in the town of Nederland, Colorado. While the town’s ordinances forbid the private keeping of remains, human or otherwise, a special clause was added for Bredo. Nederland celebrates its most unique resident the second weekend of March, and the celebrations include coffin races and a ‘frozen dead guy’ lookalike contest.

6
Waikiki Spam Jam Festival, Hawaii

Image: newhallpublishing

Hawaii is the biggest SPAM consumer in the U.S., so it’s only right that they hold a SPAM festival. Held during the last week of April, it includes fireworks, parades, live music, and all kinds of spam dishes.

7
Underwater Music Festival, Florida

Image: NEOM

Florida homes the biggest coral reef in the continental U.S., and this festival is all about it. With the intention of raising awareness for reef conservation and eco-friendly diving, this event holds an underwater concert for divers and snorkelers.

8
San Fermin, Louisiana

Image: mana5280

You might have heard of the San Fermin celebrations in Spain, where people run in front of bulls in the street. Louisiana’s San Fermin festival is similar, minus the bulls. In the New Orleans Running of the Bulls, people run from derby skaters armed with foam bats, which are aimed at anyone they encounter in their way.

9
Cow Chip Throw Festival, Wisconsin

Image: Daniel Quiceno M

Prairie du Sac, Wisconsin, certainly knows how to party on Labor weekend. Besides the chip throwing, you can enjoy music, food, and family activities. Don’t worry about bringing your own cow chips: official festival-sanctioned chips are provided to contestants to ensure fair competition.

10
North American Wife Carrying Championship, Maine

Image: Priscilla Du Preez

Wife carrying as a competitive sport was first introduced in Finland, but it has had its own festival in Newry, Maine, since 1999. Participating couples have to traverse a 278-yard obstacle course, with some of the prizes including the wife’s weight in beer and cash. Single? No problem. As long as you are 21 or older and you have a companion, you can participate.

Survival foraging in America

These 10 plants could save you from starvation

Image: Alisa Golovinska

Ever felt those hunger pangs while hiking through the countryside and wondered if you could forage to fuel up in an emergency? You absolutely can—if you know where to look. America is blessed with a variety of wild edible plants that could help you out in a pinch—and maybe even add a fresh twist to your next salad. From versatile cattails to delicious blackberries, nature’s pantry offers a surprising amount of nutrition to those who know what to seek. But remember, not every plant is safe, so don’t just sample everything you see. That’s why we’ve compiled this list of 10 common wild edible plants in the U.S. to help you forage smartly!

1
Cattails

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.

2
Dandelions

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.

3
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

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)

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

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.

7
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

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.
