Benjamin Franklin advocated for the use of paper money and even engineered some key anticounterfeiting techniques used today.

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.

Benjamin Franklin founded America's first lending library, the Library Company of Philadelphia, in 1731.

During the Civil War, the US government printed paper money for the first time

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.

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.

Benjamin Franklin donated the books that became the first true public library in the US.

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.

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.

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.

Before the US Mint, people made currency in private mints

Around the year 1652, New England coinage was created at private mints. Historically, private mints were often located in places where governments did not meet the demand for currency. This article dives into the history of private mints, including the ones people can still visit today.

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 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.

Benjamin Franklin did not invent daylight saving time. But while living in Paris, he did pen a satirical letter to Parisians suggesting they could save money on lamp oil by changing their sleep schedules. Read it in full here.

The Mint’s first circulating coins were 11,178 copper cents

Congress authorized the first national mint in Philadelphia. The next year, the Mint delivered its first circulating coins, which were bigger than today’s quarters. This article shows more early US currency.

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.

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.

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.

Benjamin Franklin once wrote a satirical essay about passing gas

The Founding Father was asked to judge a contest for the Royal Academy of Brussels, but was incensed by one of the contest's questions, which he believed was highly impractical. In response, he wrote a piece suggesting that the most essential problem for scientists to solve was the "fetid Smell" that came with passing gas.

Ben Franklin’s edit helped define the Declaration’s philosophy

When Thomas Jefferson drafted the Declaration, he wrote that its truths were “sacred and undeniable.” Benjamin Franklin urged replacing that phrase with “self-evident,” grounding the document in reason rather than religious authority and sharpening its Enlightenment logic.

In 1792, Congress established the first national mint to produce all the coins in the US

At the same time, the US also started producing the dollar, its first official currency. The US Mint has since issued coins throughout the country.

‘Mint marks’ are tiny letters on US coins that correspond to which mint location created them

As more mint branches opened up after Philadelphia (the first mint location), these “mint marks” helped hold each branch responsible for the quality of the coin. A coin minted in Philadelphia, for instance, would have the letter “P” on it. Some mint marks are extremely rare, making coins displaying them particularly valuable to collectors.

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.

The Medicis of Italy innovated 'bills of exchange,' precursors to checks

At the time, lending money for interest (also known as usury) was banned in much of the Christian world. The enterprising Medicis developed bills of exchange to allow merchants to promise payment without cash or coin (with some discrete means of earning interest woven in). Learn more about how this family laid the foundation for modern banking.

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.

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.)

Alexander Hamilton played a significant role in creating the American system of government

From 1787 to 1788, Hamilton, James Madison, and John Jay anonymously published a collection of essays known as the Federalist Papers to promote the new Constitution. Of the 85 essays that proved pivotal to the eventual ratification of the document, Hamilton wrote 51.

While the Fed is involved in issuing new generations of cash, the way it adds to the money supply does not involve printers

The majority of money in circulation is credit, not cash. This credit, which acts similarly to direct deposit from employers, is added to bank accounts by the Federal Reserve. The Fed also employs tools like the federal funds rate and open market operations to expand or contract credit.

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.

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

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.

This piece traces the Declaration's 200-year journey from its creation in 1776 through repeated relocations, risky copying methods, light damage, fires, wartime evacuation, and shifting federal custody—long before modern archival protections existed.

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.

Years of handling, copying, and light exposure have caused heavy deterioration of the original Declaration of Independence

Handwritten in gallnut ink and signed in August 1776, the Declaration endured rough handling, repeated copy attempts, and decades of exposure to air and light—leaving it heavily faded and even marked by a mysterious handprint that appeared in the early 20th century.

Hamilton created the First Bank of the United States

As Treasury secretary, Alexander Hamilton proposed the First Bank of the United States to stabilize national finances—serving as the government's fiscal agent, managing debt, and expanding credit through a public-private banking model.

Alexander Hamilton consolidated the states' debts, implemented a tax system, and established a national bank.

Throughout most of the 1800s, US currency was backed by silver and gold

Few actual Stamp Act stamps survived, as colonists destroyed nearly all of them in protest

The elaborate stamp bore royal symbols and the word "America" and was printed in Britain and shipped to the colonies to be sold by government officials. Protests erupted in nearly every colony before it could take effect, often violently targeting stamp collectors.

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

The US Currency Education Program created a guide to authenticating currency

This video was created to teach everyday people a few easy ways to spot some counterfeit banknotes. Specifically, it outlines the main security features to check for that are common across many US banknotes, such as the color-shifting ink visible when tiling US banknotes $10 or higher.

The Founding Fathers were divided in their reactions to the Boston Tea Party.

The first newspaper to report the Declaration of Independence was a German-language Philadelphia publication, simply because it was the only one that published on July 5.

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.

Benjamin Franklin described a series of static electricity storage jars as 'batteries'

Discovered over 50 years before the first electrochemical cell was invented, Leyden jars stored electric charge between the metals inside and outside a liquid-filled container. Franklin was the first to use the term "battery" in an electrical sense, though his multiple-jar device—lacking chemical reactions—was actually a series of capacitors.
