The $1 bill hasn't been redesigned in over 60 years, making it one of the least secure American banknotes from a counterfeiting and forgery perspective.

Contrary to popular belief, the $2 bill is still in circulation today, although usage has been in decline for decades.

The US has discontinued a variety of different currency denominations over the years—including a $100K bill.

Dive into the fascinating journey of a Federal Reserve note

Ever wondered how long an individual dollar bill lasts? After cash is designed and produced, money circulates in the economy, with $100 bills staying in use for the longest on average—roughly 15 years—and the $10 lasting just less than five.

America's most misunderstood dollar

The $2 bill isn't rare; it's just hiding. First printed in 1862, stopped in 1966, and revived in 1976, there are still 1.6 billion in circulation. People just don't spend them.

Some argue that the $2 bill could be more useful than the $1 bill

Inflation has made purchasing items with just a $1 bill extremely rare. At a time when dollar stores are no longer true to their name, it seems that the $2 note may be the more practical small bill to keep on hand. This article advocates for the use of $2 bills, while detailing their history of being overlooked and the communities that swear by them.

The lifespan of a dollar bill

Each design detail on the US $1 bill has significance

The eye in the triangle floating above the pyramid, for instance, is “the Eye of Providence watching over and ensuring the endurance of the structure of the American government.” This article details every design choice’s significance on the dollar—and a few conspiracies around these choices as well.

A mysterious man named Emmerich Juettner once produced thousands of counterfeit $1 bills

After his wife died in 1937, Juettner fell into financial trouble and soon began replicating $1 bills. These bills aren’t typically prime targets for counterfeiting given their low value.

There have been many versions of US banknotes throughout history

From the Civil War to the present day, the US has gone through many, many versions of paper money (or “notes”). Some notes, like “demand notes,” were created to finance the Civil War. Others, like “treasury notes,” helped pay for silver.

A dollar bill's value relies on two elements: people believing it will be accepted in exchange for goods and services, and how much demand for the currency there is.

Every printed bill has its own unique serial number

In the US, each bill also has its own plate number, series year, Treasury seal, and more. Each design helps track money and combat counterfeiting.

A ‘supernote,’ or nearly-perfect counterfeit $100 bill, was recently found in South Korea

These “supernotes” have even fooled US government officials. North Korea is widely believed to be behind the creation of these counterfeit banknotes.

That’s just one of the many anti-counterfeiting security measures that the Australian government implements on its currency. Popular banknotes from around the world all include their own unique security features—this infographic outlines a few unique ones.

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.)

Some coin denominations have ridges on their sides in part to prevent counterfeiting.

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.

Today, in the US, people can face years in prison for counterfeiting money

There are both federal and state laws that punish people who use or create counterfeit money. The crime can not only trigger hefty fines, but could also lead to decades behind bars.

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.

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

Those original paper bills were called “greenbacks” or “demand notes.” Since then, paper money has evolved with different designs, names, and values. Today, it is solely issued by the Bureau of Engraving & Printing.

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 designs on US coins have changed a lot over the years

From states producing and issuing their own coins after the Revolutionary War, to collectors’ coins in modern times, US coins have had many design changes throughout history. You can learn about the different variations, plus what design elements are added to all US coins today, in an article.

Harriet Tubman will be featured on the $20 bill in 2028

Governments have historically used counterfeiting for economic warfare

Inserting fake currency into an economy can help destabilize it. During the American Revolution, for instance, the British distributed counterfeit “Continental Dollars” in an effort to devalue the currency being used in the US at the time with the goal of undermining America’s growing financial credibility. The Nazis also ran an extensive counterfeiting scheme during WWII.

The US dollar is the official currency of the United States and is the most circulated currency around the world

The US dollar was established in 1792 and comes in the form of coins or paper money. It's considered one of (if not the most) stable currencies in the world due to America’s strong and robust economy, as well as its relatively stable government.

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

The Eye of Providence on $1 bills is a lightning rod for conspiracy theorists

The symbol is associated with the Freemasons, one of the world’s oldest secret societies. It also appears on churches, Masonic buildings, and the great seal of the United States.

The case against the penny

It takes roughly three cents to produce a single penny, with an annual price tag of nearly $100M. The ubiquitous copper coin is scarcely used, ending up in jars or lost in couches, necessitating even more replacement coins, perpetuating a vicious circle. Studies suggest eliminating the coin would not cost consumers money. See a quick overview of the problem here.

The US developed a coin circulation problem in 2020

As people reduced the frequency with which they paid for things in cash and change during the COVID-19 pandemic, opting for tap-to-pay systems or online shopping instead, the number of coins in circulation decreased. Those who did make cash purchases were more likely to keep their change at home rather than use it on a subsequent purchase.

Thomas and Anne Rogers were famous counterfeiters in 17th-century England

The pair used a practice called “coin clipping,” shaving the edges off silver coins to decrease their weight before sending them back into circulation. When banknotes rather than coins gained popularity, counterfeiting methods evolved—in the 1700s, an early banknote counterfeiter named Mary Butterworth created counterfeit paper money using starched cloth and a hot iron to transfer the pattern of a banknote onto paper.

How US currency is issued

Cash in the US is the result of a collaborative process between the Federal Reserve, the Treasury Department, regional banks, and a little-known agency called the Bureau of Engraving and Printing. From design to issuance, learn the steps in currency production in the US with this smart, aesthetic interactive.

Customers wrote just one check a year in 2024, on average

Major retailers like Target have stopped accepting checks in recent years as real-time payment systems are increasingly being implemented across the US. This shift is considered an improvement in safety—as checks are vulnerable to fraud—but can lead to some exclusion for those without access to digital devices.

Why there are microchips in credit cards

Credit cards have evolved significantly since their invention in 1950, but security lagged in the US for years. Despite handling only a quarter of global transactions, the US once accounted for half of all credit card fraud. The 2013 Target data breach helped push the adoption of chip cards, reducing fraud but shifting risks to online scams.

The US dollar has served as the world's reserve currency for 80 years—but is its dominance coming to an end?

Since the establishment of the Bretton Woods economic system, about 90% of global foreign exchange transactions have involved USD. Although no viable alternative exists yet, the dollar's share of central bank reserves has decreased from 73% to 58% from 2001 to 2024, and President Trump's 2025 tariffs have sped up this trend.

10 of the original 14 copies of the Bill of Rights still exist

Clerks produced 13 copies for the states, plus one federal copy. Today, eight states still hold theirs. Georgia's and New York's were likely burned, Pennsylvania's was stolen, and Maryland's whereabouts remain unknown.

Early Americans hated the idea of a central bank

After a series of economic panics induced by a lack of reserve cash at regional banks, the architects of today’s Federal Reserve opted to emphasize the goal of the bank as a reserve at the federal level—thus creating the lasting name.

Minting a coin that can pay off the federal debt has been proposed as a quick fix to rampant borrowing.

The Federal Reserve is the most powerful financial institution in the US

The Fed controls the money supply, determines interest rates, and regulates the banking system. Established in 1913 after a volatile series of financial panics, the central bank has managed to retain its legitimacy despite broad critiques against its obscure and independent decision process.

Colonial Americans used tobacco, wampum, and land-backed notes to solve a chronic coin shortage

British coins rarely circulated in the colonies due to an unfavorable trade balance, forcing colonists to improvise. They traded in Spanish dollars, Native American shells, tobacco warehouse receipts, and eventually paper money backed by land rather than gold.

The Bill of Rights spent more than a century largely ignored by the courts

When ratified in 1791, the Bill of Rights applied only to the federal government, which exercised little direct control over daily life. It played a limited role in early constitutional law until the 20th century, when legal advocates began using it to challenge state and local laws.

No institution wields more power in US finance than the Federal Reserve, the central bank of the US—but opinion polls indicate that most Americans don't know what it does.
