Hoosier

Until recently, the United States Government Publishing Office (or USGPO) still recommended Indianian as the demonym for the state of Indiana, but its residents have been calling themselves Hoosiers for nearly two centuries. While no one really knows where the term originated, it was popularized by John Finley’s poem "The Hoosier's Nest", and Indiana has long been known as "The Hoosier State".

Bay Stater

The USGPO might recommend the use of Massachusettsan , but the people of Massachussets strongly disagree. State laws and regulations officially refer to its residents as Bay Staters , after a common nickname for the state. Given that Massachusetts is formally a Commonwealth, the law also uses the phrase Citizen of the Commonwealth , but it's kind of a mouthful for everyday purposes. We’ll stick with Bay Stater.

Accidental

One of the earliest settlements in Maryland, the town of Accident is not very big, but it makes up for it with its peculiar name. Naturally, the corresponding demonym for its residents is Accidental , though some sources also claim that the citizens of Accident are to be called Accidents .

Granite Stater

Much like Bay Staters, the residents of New Hampshire tend to disagree with the USGPO when it comes to their demonym. The official version is New Hampshirite (for the Federal Government, at least ), but locals favor the term Granite Stater , derived from New Hampshire’s nickname, "The Granite State".

Truth-or-Consequencesan

When the town of Hot Springs, New Mexico, decided to change its name to Truth or Consequences for a radio show contest, they either forgot to consider their new demonym or didn’t really care. While they are technically Truth-or-Consequencesans , they refer to the town as T or C, so they say that they are Residents of T or C .

Phoenician

Weren’t the Phoenicians an ancient civilization that created the earliest form of our alphabet? Yes, but those lived in ancient Phoenicia. The Phoenicians we are talking about are the residents of Phoenix, Arizona. Some claim that Zoner and Zonan are also common nicknames, but those could be used for any Arizona resident.

Nutmegger

Connecticut might be officially known as "The Constitution State", but it’s also called "The Nutmeg State". The origin of this nickname varies according to the sources, but most point to a common scam where Connecticut peddlers would sell wooden nutmegs as the real thing. No matter the story, many Connecticut residents favor the demonym Nutmegger over the USGPO-recommended Connecticuter .

Yoopers

Let’s be frank, some of the less-used variants for Michigan’s demonym sound really funny: think Michiganese , Michigine , and Michigoose (as a female version for Michi_gander_). But official names aside, residents of Michigan’s Upper Peninsula commonly refer to themselves as Yoopers , a derivative of U.P. (Upper Peninsula). Rumor has it that they call those from the Lower Peninsula Trolls , because they live ‘under the bridge’, but we can’t attest to this being true.

Jayhawk

Image: Nils Huenerfuerst

Nowadays, Jayhawk is a common way to refer to residents from Kansas, but this term didn’t always have a positive connotation. Its original form, Jayhawker, used to refer to thieves, and was used derogatively by Confederates to talk about the anty-slavery militias from Kansas. After the Civil War, Kansans appropriated the term as a memento of their state’s contributions to the war.

Lanstronaut

Officially, if you live in Lansing, Michigan, you are a Lansingite . However, many Lansing residents have taken to using the term Lanstronaut in recent years, despite Lansing having more to do with the car industry than with space.

Clock change

Image: Jonathan Borba

US currency is full of symbolism, and the $100 bill is no exception. Since 1928, we have seen Independence Hall depicted on the back of this bill. But in 2013, it was redesigned, and one change stands out: the clock tower, which previously showed 4:10, now reads 10:30. Did you notice?

Jackie Kennedy’s choice

Image: Florida Memory

Jackie Kennedy played a key role in designing the coin that would feature the portrait of her ex-husband. When the U.S. Mint planned the Kennedy half dollar in 1964, she was consulted and provided input on various aspects of the coin, including its imagery and symbolism.

3

Not paper

Image: Giorgio Trovato

Although it is called paper money, our bills do not contain any paper at all. In fact, they are made of a blend of 75% cotton, 25% linen, and fine silk fibers embedded. This mixture is not random; it was specially chosen so that your bills can withstand everything: folds, wrinkles, stains, and even an accidental shower in the washing machine.

4

The unfinished pyramid

Image: Marek Studzinski

The one-dollar bill also has its secrets and details. On its back, you’ll find an unfinished pyramid, part of the Great Seal of the United States designed in the 1780s. Why unfinished? The pyramid has 13 steps, representing the original 13 colonies, and its incomplete form symbolizes the nation’s ongoing growth and expansion.

50% larger

Image: Bozhin Karaivanov

Before 1929, US banknotes were significantly larger, measuring approximately 7.375 x 3.125 inches. Today, collectors refer to these as "large-size" notes, sometimes even nicknamed "Horseblankets." In contrast, modern bills measure just 6.14 x 2.61 inches. The government decided to reduce the bill's size to cut production and design costs.

6

Andrew Jackson’s preference

Image: Giorgio Trovato

Andrew Jackson has been the face of the $20 bill since 1928, when he replaced Grover Cleveland. Ironically, Jackson was opposed to paper money. He didn't trust that form of payment, believing it could be easily manipulated. According to historians, the 7th U.S. President favored "hard money": gold and silver coins.

Alexander Hamilton’s portrait

Image: engin akyurt

Most portraits on US bills face left, with one exception: Alexander Hamilton on the $10 bill, the only one facing right (toward the viewer’s left). You might wonder why, but there’s no official explanation; it seems to have been simply a design choice.

"In God We Trust"

Image: rc.xyz NFT gallery

In 1956, Congress passed a law declaring "In God We Trust" the national motto, making it mandatory on all U.S. coins and banknotes. But this wasn’t its first appearance: the phrase first appeared in 1864 on the two-cent coin. Beyond faith, it also carried political weight, suggesting that God favored the Union during the Civil War.

9

The change that never happened

Image: Ryan Quintal

In 2015, the Treasury announced plans to redesign the $10 bill, stating that Hamilton's portrait would be replaced by that of an influential woman from US history. However, the change never happened. Why? Those years saw a surge in Hamilton's popularity thanks to the hit musical of the same name, leading the Treasury to backtrack on the replacement plan.

Criteria

Image: Live Richer

As is well known, not just any portrait can appear on US currency. But beyond historical significance, the figures on our bills and coins must meet other criteria you might not know: They must also be deceased and well recognized by citizens, ensuring that the people represented are familiar and meaningful to the public.

1

The horse diaper

Image: Lucia Macedo

Designed to catch manure in crowded cities—a problem once so severe that it shaped public infrastructure as well as the entrances to houses—the horse diaper was an invention meant to be strapped beneath working horses pulling carts and carriages.

The idea was to reduce disease and street filth during the horse-powered urban era. While the device saw limited use before automobiles rapidly replaced horses, similar designs are still occasionally used in modern veterinary practice.

2

The baby cage

Image: Taylor Flowe

Built as wire cages attached to apartment windows, so-called "baby cages" allowed infants to get fresh air when outdoor space was unavailable. Some models were guaranteed to safely hold over 30 pounds.

While alarming today and ultimately abandoned due to obvious safety concerns, the designs likely inspired some of the baby-proofing nets used today.

3

The pneumatic subway

Image: Eddi Aguirre

In the late 1860s, American entrepreneur and inventor Alfred Ely Beach set out to prove the feasibility of a human-sized pneumatic subway system beneath New York City, capable of moving both people and cargo using nothing more than air pressure.

The prototype was set up as a public attraction and carried passengers along a tunnel just over 300 feet long, from a station to a dead end. Despite its initial success, bureaucratic obstacles and high costs halted expansion, leaving it as a functional but largely forgotten underground experiment.

4

The mechanical horse

Image: Gabriel Tovar

Created for exercise and riding practice, the mechanical horse used a system of gears, cranks, and pedals to simulate walking and trotting motions while the rider sat in a saddle-like seat. It was marketed to urban riders and cavalry trainees who lacked access to stables or live horses.

Though bulky and impractical for widespread use, the device anticipated modern fitness machines by replicating real-world movements for conditioning and skill retention, rather than simple repetitive exercise.

5

The first metal detector

Image: Fer Troulik

After a failed assassination attempt on President James Garfield, Alexander Graham Bell hastily built an early metal detector in an effort to locate the bullet lodged in his body. The device functioned as intended, but it was unable to find the bullet because metal bed springs interfered with the signal.

Despite this setback, Bell’s early design proved the concept and directly influenced the development of modern metal detectors.

6

The pet-powered butter churn

Image: Matt Bero

In an inventive twist on animal-powered machinery, some 19th-century American farmers rigged small treadwheels for dogs, cats, or even goats to generate kinetic energy for churning butter. The animal ran inside the wheel, turning a rope or pulley connected to the churn.

While technically functional, the system was limited by the animal's willingness to cooperate and the small amount of power it generated.

7

The umbrella hat

Image: Claudio Schwarz

Robert W. Patten, often called the "Umbrella Man," patented one of the first commercially successful hands-free umbrella hats. It strapped a small umbrella directly to the wearer’s head, providing both sun and rain protection while keeping the hands free for work or walking.

His original design even included a mosquito net attached to the canopy. Patten didn’t enjoy much commercial success but became somewhat of an eccentric and comical popular figure, partly due to a series of comics that were inspired by his unusual invention.

8

The one-wheel motorcycle

Image: CJ Toscano

In 1971, American inventor Kerry McLean built and refined a monowheel—a one‑wheeled motorized vehicle in which the rider and engine sit inside the wheel’s circumference.

Since then, various attempts have been made to build on his original design, but it remains a niche vehicle used primarily for entertainment rather than practicality, as riders must be highly skilled simply to turn or even stay upright.

The first talking doll

Image: Holly Ward

In 1890, Thomas Edison embedded miniature versions of one of his most popular inventions —the phonograph—inside dolls so they could recite nursery rhymes.

While the idea was innovative, the technology was not yet there. The recordings were fragile, distorted, and often failed to work properly. The dolls were pulled from the market within weeks due to customer complaints, making it one of Edison’s rare commercial failures.

The glass harmonica

Image: Francesco Bovolin

Faithful to his eccentricity and inventive spirit, Benjamin Franklin redesigned the existing glass harp into a rotating spindle of glass bowls, played by touching the spinning rims with wet fingers, which he called the "glass harmonica."

The instrument produced eerie, sustained tones unlike anything else of its era. However, its fragile nature made it somewhat impractical, and the rotating mechanism posed a potential danger to the player if anything went wrong.
