The portrait of George Washington was first placed on the one-dollar bill in 1869

The US has used a wide variety of different currencies between the 1690s and today

From colonial money to national banknotes, people have used all kinds of forms of currency throughout the history of the United States before settling on the dollar bills and quarters that we pay for things with today.

Hamilton has appeared on US paper currency since the Civil War

Since the US began printing money in 1861, Alexander Hamilton has appeared at different times on the $5, $2, $20, $50, $500, and $1000 bills. Since 1928, he has remained on the $10 bill—making him, alongside Benjamin Franklin, one of the two non-presidents currently on US currency.

Madison's portrait was on the now-defunct $5,000 bill

James Madison appeared on the $5,000 bill, a high-denomination note used primarily for bank-to-bank transactions that was discontinued in 1969 as electronic payments reduced the need for large paper currency. (The rare note is still legal tender, though it is often worth much more than its face value to collectors.)

The United States had a washing machine that cleaned dirty dollar bills

In the early 1900s, the US Treasury Department had a machine that washed and ironed old, soiled paper bills. The machine helped the Treasury save money by decreasing printing costs for new dollar bills, but had nothing to do with the modern understanding of money laundering.

The 'Where's George?' project tracked a trail of $1 bills across the US

The dollar’s value stems from public trust and demand

In simple terms, a dollar bill’s value relies on two elements: that people believe it will be accepted in exchange for goods and services, and how much demand for the currency there is.

George Washington set the template for the presidency

As the first US president, George Washington established key traditions still followed today—forming a Cabinet, serving only two terms, asserting executive independence, and peacefully transferring power—helping define how the presidency would function.

The Secret Service was originally formed to combat counterfeiting

By the 1860s, an estimated one-third of US currency in circulation was counterfeit. In 1865, the Secret Service was created specifically to combat the country's serious counterfeiting problem, which had led to widespread financial instability. This was partly due to the lack of federal currency standardization in the country at the time.

Hamilton built the foundations of the US financial system as the nation's first Treasury secretary

Appointed the nation's first Treasury secretary in 1789 by George Washington, Alexander Hamilton designed a powerful federal finance system—repaying war debts, creating new taxes, founding a national bank, and promoting economic development.

The evolution of the State of the Union speech

The US State of the Union speech is an annual event proposed by the country's Constitution and scheduled by its first president. President George Washington was the first to deliver such a speech, by nature of his office, limiting the inaugural "Annual Message" to 1,100 words and 10 minutes. Just 10 years later, the country's second president, John Adams, changed the nascent tradition, instead offering a written statement.

Washington sat for a portrait at least 12 times during his career

Those sittings were primarily for painter Charles Willson Peale. Without photographs, capturing the accurate physique of the tall, commanding Washington is difficult—but you can get a sense of his appearance with this collection of paintings over several decades.

Washington systematically introduced and popularized mule breeding in the United States

Known as "the father of the American Mule," Washington imported a prized Spanish donkey and bred it with a female horse at Mount Vernon. He promoted mules as stronger, more efficient farm animals, helping spread their use across the South and transforming American agriculture.

The Civil War turned the Continental Divide into an American symbol of identity

Historians argue that the boundary only became a celebrated American symbol in the 1860s, when Civil War-era leaders promoted a west-east geographic divide to replace the devastating north-south political divide, and that the term's use spiked after the transcontinental railroad crossed it in 1868.

Many myths continue to circulate about the first Thanksgiving

The Thanksgiving myth didn’t really start in 1621, argues historian David Silverman in this interview with Smithsonian. Rather, it took hold over 200 years later. During the Civil War, Thanksgiving was declared a national holiday by Abraham Lincoln as a way to promote national unity. The tidy story of friendship between Native Americans and colonists was used to quell racial tensions of the late 19th century.

Watch how the Stamp Act in 1765 sparked the American Revolution

The reaction to the first direct tax on colonists prompted the second-ever colonial congress and a broad boycott of British goods. It also gave birth to the Declaration of Rights and Grievances, the congress's document articulating the "no taxation without representation" stance. The act's passage was a major stepping stone to revolution.

The original copy of the Declaration of Independence is not a pristine document, and even features a smudged anonymous handprint in the bottom left corner.
