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 infographic below, Visual Capitalist's Avery Koop and Mark Belan have 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.

? 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.

? 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.
