Visualized: The Security Features of American Money
In 1739, Benjamin Franklin sought to tackle the issue of counterfeit money in America, using a printing press and leaves to create unique raised patterns on the colonial notes.
Almost 300 years later, Benjamin Franklin is the face of the U.S. $100 bill, and it is protected by a myriad of security features including secret images, special ink, hidden watermarks, and magnetic signatures, among others.
In this visual, we’ve broken down the $100 bill to showcase the anatomy of American currency.
The Makeup of American Money
There are 6 key features that identify real bills and protect the falsification of American money.
① Serial Numbers & EURion Constellation
The most basic form of security on an $100 bill is the serial number. Every bill has a unique number to record data on its production and keep track of how many individual bills are in circulation.
The EURion constellation is star-like grouping of yellow rings near the serial number. It is only detectable by imaging software.
② Color Changing Ink
This ink changes color at different angles thanks to small metallic flakes within the ink itself. The $100 bill, like all other paper bills in the U.S., has its value denoted in color changing ink on the bottom right-hand corner; unlike other bills, it also features a liberty bell image using the ink.
③ Microprinting
Microprinting allows for verifiable images that cannot be scanned by photocopiers or seen by the naked eye. The $100 bill has phrases like “USA 100” written invisibly in multiple places.
④ Intaglio Printing
Rather than regular ink pressed onto the paper, intaglio printing uses magnetic ink and every different bill value has a unique magnetic signature.
⑤ Security Threads & 3D Ribbons
The security thread is a clear, embedded, vertical thread running through the bill. It can only be seen under UV light, contains microprinted text specifying the bill’s value, and on each different bill value it glows a unique color.
Additionally, 3D ribbons are placed in the center of $100 bills with a pattern that slightly changes as it moves.
⑥ Paper, Fibers, & Watermarks
Because American money is made of cotton and linen, blue and red cloth fibers are woven into the material as another identifying feature. Finally, watermarks are found on most bills and can only be detected by light passing through the bill.
The Relevance of Cash
Here’s a look at the total number of each paper bill that is physically in circulation in the U.S.:
Physical Bill | Billions of notes (2021) |
---|---|
$1 | 14.0 |
$2 | 1.4 |
$5 | 3.4 |
$10 | 2.3 |
$20 | 11.9 |
$50 | 2.5 |
$100 | 17.7 |
$500-$10,000 | 0.0004 |
Total | 53.2 |
Interestingly, a number of $500-$10,000 dollar bills are in someone’s pockets. And while they are not issued anymore, the Fed still recognizes the originals of these bills that were legally put into circulation in the past.
Additionally, there is fake money passing hands in the U.S. economy. Being the most widely-accepted currency in the world, it’s no wonder many try to falsely replicate American money. According to the U.S. Department of Treasury, there are approximately $70 million in counterfeit bills currently circulating in the country.
Finally, a natural question arises: how many people still use cash anyways?
Well, a study from Pew Research Center found that it while it is a dwindling share of the population, around 58% of people still use cash for some to all of their weekly purchases, down from 70% in 2018 and 75% in 2015.

The Richest People in the World in 2023
The world’s five richest people are worth a combined $729 billion. From luxury moguls to Asia’s rising titans, we show the richest in 2023.

The Richest People in the World in 2023
After witnessing record gains in wealth, ultra-high net worth individuals (UHNWIs) lost a combined $10 trillion last year.
A lagging stock market dented these fortunes against high interest rates, energy shocks, and economic uncertainty. But some of the world’s billionaires have flourished in this environment, posting sky-high revenues in spite of inflationary pressures.
With data from Forbes Real-Time Billionaires List, we feature a snapshot of the richest people in the world in 2023.
Luxury Mogul Takes Top Spot
The world’s richest person is France’s Bernard Arnault, the chief executive of LVMH.
With 75 brands, the luxury conglomerate owns Louis Vuitton, Christian Dior, and Tiffany. LVMH traces back to 1985, when Arnault cut his first major deal with the company by acquiring Christian Dior, a firm that was struggling with bankruptcy.
Fast-forward to today, and the company is seeing record profits despite challenging market conditions. Louis Vuitton, for instance, has doubled its sales in four years.
In the table below, we show the world’s 10 richest people with data as of February 27, 2023:
Rank | Name | Source | Net Worth Feb 2023 | Change 2022-2023 |
---|---|---|---|---|
1 | Bernard Arnault & family | LVMH | $202B | 28% |
2 | Elon Musk | Tesla, SpaceX | $191B | -13% |
3 | Jeff Bezos | Amazon | $117B | -32% |
4 | Larry Ellison | Oracle | $113B | 7% |
5 | Warren Buffett | Berkshire Hathaway | $106B | -10% |
6 | Bill Gates | Microsoft | $105B | -19% |
7 | Carlos Slim Helu & family | Telecom | $90B | 11% |
8 | Mukesh Ambani | Diversified | $84B | -8% |
9 | Steve Ballmer | Microsoft | $81B | -11% |
10 | Françoise Bettencourt Meyers & family | L'Oréal | $79B | 5% |
Elon Musk, the second-wealthiest person in the world has a net worth of $191 billion. In October, Musk took over Twitter in a $44 billion dollar deal, which has drawn criticism from investors. Many say it’s a distraction from Musk’s work with Tesla.
While Tesla shares have rebounded—after falling roughly 70% in 2022—Musk’s wealth still sits about 13% lower than in March of last year.
Third on the list is Jeff Bezos, followed by Larry Ellison. The latter of the two, who founded Oracle, owns 98% of the Hawaiian island of Lanai which he bought in 2012 for $300 million.
Fifth on the list is Warren Buffett. In his annual letter to shareholders, he discussed how Berkshire Hathaway reported record operating profits despite economic headwinds. The company outperformed the S&P 500 Index by about 22% in 2022.
How Fortunes Have Changed
Given multiple economic crosscurrents, billionaire wealth has diverged over the last year.
Since March 2022, just four of the top 10 richest in the world have seen their wealth increase. Two of these are European magnates, while Carlos Slim Helu runs the largest telecom firm in Latin America. In fact, a decade ago Slim was the richest person on the planet.
Jeff Bezos has seen his wealth decline 32%, or $54 billion, the most across the top 10 richest. Amazon posted a $2.7 billion net loss for the full year of 2022, its worst year yet.
Overall, as the tech sector saw dismal returns over the year, the top 10 tech billionaires lost almost $500 billion in combined wealth.
Recent Shakeups in Asia
Perhaps the most striking news for the world’s richest centers around Gautam Adani, formerly the richest person in Asia.
In January, Hindenburg Research, a short-selling firm, released a report claiming that the Adani Group engaged in stock manipulation and fraud. Specifically, the alleged the firm used offshore accounts to launder money, artificially boost share prices, and hide losses.
The Adani Group, which owns India’s largest ports—along with ports in Australia, Sri Lanka, and Israel—lost $100 billion in value in the span of a few weeks.
Interestingly, very few Indian mutual funds hold significant shares in Adani Group, signaling a lack of confidence across India’s market, which was also cited in Hindenburg’s report.
As a result, Mukesh Ambani has climbed to Asia’s top spot, controlling a $84 billion empire that spans from oil and gas and renewable energy to telecom. His conglomerate, Reliance Industries is the largest company by market cap in India.
