Did you know that, for a time, there was a $10,000 bill? That's right! The bill featured the portrait of Salmon P. Chase, President Lincoln's Secretary of the Treasury, and it was the highest denomination of US currency ever to be publicly circulated! While there was also a $100,000 bill, the latter was only used for large transactions between Federal Reserve Banks.

The first President on a coin

Image: Sebastian Enrique

We're totally used to seeing Abraham Lincoln's face on a penny, but that wasn't always the case.

Lincoln's image first appeared on the penny in 1909 to commemorate the 100th anniversary of his birth, making him the first US president to appear on a coin, an honor befitting our great Honest Abe! More than 115 years have passed since that addition, and his face is still featured on the iconic penny.

Silver pennies

In addition to featuring Abraham Lincoln's face, pennies are famous for their classic copper color. However, there was one year when the penny took on a different hue.

During WWII, a copper shortage occurred, hindering the usual production of pennies. For that reason, in 1943, pennies were made of steel coated in zinc, giving them a silver color and making them closely resemble dimes.

Did you know that, in the 19th century, the US had 2- and 3-cent coins? That's right! The 2-cent coin was minted from 1864 to 1873. On the front, it featured a shield symbolizing the Union during the Civil War . On the reverse, it bore the phrase "In God We Trust," making it the first coin to use the motto . The 3-cent coin had two versions: the silver 3-cent coin (1851–1873) and the nickel 3-cent coin (1865–1889).

Long lifespan

While each coin is used with a different frequency, the average lifespan of a coin can be as long as 40 years ! Just think about all the places and situations it might pass through during that time. Of course, the more a coin circulates, the quicker it will wear down. That’s why the penny has the shortest lifespan , lasting about 25 years on average.

In God We Trust

"In God We Trust" is not only the official motto of the United States (and the state of Florida), but also the phrase that appears on all US currency currently in circulation. But how long has this phrase been there?

"In God We Trust" first appeared on some coins during the Civil War, starting with the aforementioned 2-cent piece. By 1938, the motto appeared on all US coins, but it wasn't until 1955 that President Eisenhower signed a law requiring "In God We Trust" to be included on all US coins and paper money.

Precious metals

Today, US coins are primarily made of zinc, copper, and nickel. However, back in the early days of the US Mint, things were quite different. In the past, US coins were made not just of copper, but also of silver and even gold!

Over time, using those materials for coins became too expensive, and production shifted to more affordable metals such as zinc and nickel.

Safety edges

When coins were made of precious metals like gold and silver , there was always the risk that someone might tamper with or shave the edges to extract the valuable material. Fortunately, the brilliant Isaac Newton came to the rescue. He introduced the clever idea of adding reeded edges to coins, which helped protect them from opportunistic tampering. With these marked edges, any shaving of the coin would be immediately noticeable. Pretty smart, right?

The most coins in the world

The US Mint manufactures billions of coins each year for circulation, and while that’s nothing new, there’s something about it that might surprise you: the United States is actually the world’s largest producer of coins . No other country makes more!

Pennies, nickels, dimes, and quarters are produced in large quantities every day. But that’s not all—dollar coins and special collectors’ coins are also minted, though in much smaller amounts.

"Paper" currency

Our paper money isn’t actually made of paper . It’s composed of 25% linen and 75% cotton. This blend gives US bills greater strength and flexibility, making them not only more durable but also more difficult to counterfeit. Plus, if you accidentally toss a buck in the washing machine, there’s a good chance it’ll come out just fine!

George Washington - The whiskey-making Founding Father

Image: Daniel Vogel

After leading the nation, George Washington stepped into the world of spirits, whiskey spirits, that is! In 1797, his farm manager convinced him to open a distillery at Mount Vernon . Within two years, it became one of the largest in the country, producing nearly 11,000 gallons of whiskey annually.

Here’s a fun fact: Washington didn’t need a marketing team. His whiskey was sold in unmarked barrels to local merchants, and his operation was so successful that it became one of the top money-makers in the area. The best part? You can try it today at the reconstructed distillery!

Not one to sit still, Theodore Roosevelt went on an exploration of the Amazon rainforest after leaving office. In 1913, he embarked on a seven-month journey to map an uncharted river . Guess what it’s called today? The Roosevelt River, of course!

The expedition was grueling: he caught malaria, suffered a leg injury, and nearly died. Though he made it back home, his health never fully recovered. Roosevelt’s post-presidency was all about adventure and risks!

Thomas Jefferson - The University Founder

Image: Ryan Ledbetter

Thomas Jefferson didn’t just help write the Declaration of Independence; he also founded the University of Virginia . A firm believer in education, he wanted to create a university that emphasized academic freedom and rigorous learning. So, in 1819, ten years after leaving office, he established the University of Virginia, which opened in 1825.

Jefferson personally designed the campus, including its iconic Rotunda, and hand-picked the first professors. He once called the university one of his greatest accomplishments, right up there with drafting the Declaration of Independence.

John Quincy Adams - From President to Congressman

Image: Ian Hutchinson

John Quincy Adams didn’t believe in retirement, you know? He didn’t go back for a second term, but instead of stepping away from public service, he returned to Congress, serving in the House of Representatives for nine terms until his death in 1848.

His dedication earned him the nickname "Father of the House." Even in his final moments, he was working: he collapsed on the House floor after casting a vote and died two days later. Well, once a public servant, always a public servant.

William Howard Taft - From President to Supreme Court Justice

Image: Adam Michael Szuscik

Most former presidents take a step back from government, but William Howard Taft went in the opposite direction. After serving as the 27th president, he was appointed Chief Justice of the Supreme Court in 1921.

He later admitted that being on the Supreme Court was his true calling, famously stating, "I don’t remember that I ever was president." Taft remains the only person in history to have served in both roles! Talk about an upgrade!

Calvin Coolidge - Presidential columnist

Some former presidents write memoirs, but Calvin Coolidge took it a step further. From 1930 to 1931, he wrote a nationally syndicated newspaper column titled Thinking Things Over with Calvin Coolidge .

His articles covered a range of topics, from politics to everyday life. As it turns out, running a country gives you plenty to write about!

Jimmy Carter - The humanitarian president

If there’s one president who redefined life after the White House, that is Jimmy Carter. In 1982, he founded the Carter Center , a nonprofit organization focused on democracy, health, and human rights.

He has also spent decades working with Habitat for Humanity, personally helping to build homes for those in need. In 2002, Carter’s humanitarian work earned him the Nobel Peace Prize, making him the only former president to receive the honor for efforts made after leaving office. He once said his post-presidency was "more gratifying" than his time in politics. Only logical, right?

Ronald Reagan - A Knight of the Realm

Image: Annie Spratt

Yes, that’s a literal title. Ronald Reagan didn’t take up a new career after leaving office, but he did receive an unexpected knighthood from Queen Elizabeth II. In 1989, just months after stepping down as president, he was made a Knight Grand Cross of the Most Honorable Order of the Bath.

While it’s a prestigious honor, American citizens aren’t allowed to use the title "Sir," so there was no "Sir Ronald" in the works. Reagan wasn’t the only president to receive this honor; Dwight Eisenhower and George H.W. Bush were also knighted.

Bill Clinton - Grammy-winning storyteller

Image: Annie Spratt

Bill Clinton has always been a gifted speaker, so it’s no surprise that he won not one, but two Grammy Awards, though they weren’t for playing his famous saxophone. He won Best Spoken Word Album in 2004 and 2005, narrating both a children’s book and his autobiography.

Clinton joins a small but prestigious club of American presidents who have won Grammys, including Barack Obama and Jimmy Carter. His ability to captivate audiences didn’t end with politics; he simply found a new stage.

George W. Bush - From the White House to the Art Studio

Image: Yannis Papanastasopoulos

After serving two terms as president, George W. Bush discovered a surprising new passion: painting. How about that? In 2012, he began taking art lessons , and by 2013, his paintings were revealed to the public following an email hack.

Bush embraced his new hobby and has since published several collections, including Portraits of Courage , which features paintings of US military veterans. His artwork has been exhibited in galleries, proving that a president can become an artist, too. While politics was his career, painting has become his personal form of expression.

1851: Early refining emerges

Image: Cedrik Wesche

Just before the drilling boom, chemists like Samuel Kier developed small stills to refine crude oil into kerosene for lamps.

That innovation turned oil from a curiosity into a practical commodity. Kerosene replaced whale oil, making lighting cheaper and more widely available, and it created demand for a reliable crude supply.

1859: First commercial well

Image: Provincial Archives of Alberta

On August 27, 1859, Drake Well near Titusville, Pennsylvania, drilled by Edwin L. Drake, became the first purposefully drilled commercial oil well in U.S. history.

This moment ignited the first true American oil boom. Suddenly, it was possible to produce large volumes of crude—not just collect surface seepage—and to refine it into useful fuels.

1860s–1870s: Pennsylvania oil rush

Word of the Drake success spread fast, and drilling spiked throughout Pennsylvania. Towns such as Titusville swelled almost overnight as wells and refineries spread along Oil Creek Valley.

Railroads extended into western Pennsylvania to transport oil across the country, embedding petroleum into America’s emerging industrial infrastructure.

1890s: Dawn of the automobile

Image: Matthew Lancaster

By the 1890s and into the early 20th century, the rise of the automobile created growing demand for gasoline , which had previously been a relatively minor byproduct of crude oil refining.

This shift moved oil’s primary role away from lighting and industrial lubrication and toward transportation fuel , setting the stage for petroleum to dominate America’s energy needs in the decades that followed.

1900s–1910s: Rise of big oil companies

Image: Russel Bailo

Following early successes, oil refining and distribution consolidated. Firms like Standard Oil Company rose to dominate refining, pipelines, and distribution networks.

At the same time, new oil fields and competition still challenged monopolies and spread oil wealth and infrastructure across more regions of the country.

1914–1945: Oil & war

Image: Roman

During both World War I and World War II, U.S. oil production and refining capacity became critical to the Allied war effort , fueling ships, vehicles, aircraft, and manufacturing.

That strategic role cemented oil’s position not only in industry but also in American global power, military strategy, and foreign policy.

1960: A global oil cartel forms

Image: Christian Harb

On September 14, 1960, the main oil‑exporting nations formed the Organization of the Petroleum Exporting Countries (OPEC) to coordinate oil production and influence prices globally.

Though initially limited in power, OPEC’s rise began to challenge American dominance , setting the stage for decades of geopolitical tension around oil supply.

1969: Santa Barbara oil spill

Image: matt brown

In early 1969, a blowout from an offshore drilling platform released tens of thousands of barrels of oil into the waters off California’s coast, devastating marine life and beaches.

The resulting public outrage helped trigger a surge in environmental awareness and regulation, marking a turning point in how the oil industry was perceived socially and politically.

1970–1973: Peak and decline

Image: Documerica

By 1970, U.S. conventional oil production reached its peak, but soon after began a decline as domestic fields matured and couldn’t keep up with the growing demand.

As American production fell, the country gradually became more reliant on foreign oil, a shift that would have major economic and political repercussions.

2000s–2010s: Top oil producer again

Image: engin akyurt

In the early 2000s, engineers refined techniques like hydraulic fracturing and horizontal drilling. This unlocked vast shale‑oil and shale‑gas reserves previously uneconomical to tap.

From about 2010 onward, U.S. crude oil production rose sharply, reversing decades of decline. By 2019, the country was producing at levels not seen since the early 1970s.
