The $100 bill is the highest denomination of U.S. currency in general circulation. To combat counterfeiting, it incorporates a range of advanced security features. This article details those features, making it easier to identify a genuine $100 note.
Key Security Features of the $100 Bill
The redesigned $100 bill, first issued in 2013, includes several distinct security features designed to deter counterfeiting.
3D Security Ribbon
A blue ribbon to the right of Benjamin Franklin’s portrait contains images of bells and “100s” that shift and move as the note is tilted. When tilting the note back and forth, the images move side to side. Tilting it side to side causes the images to move up and down. This ribbon is woven into the paper, not printed on it.
Bell in the Inkwell
To the right of the 3D Security Ribbon is a copper inkwell containing a color-shifting bell. As the note is tilted, the bell changes color from copper to green, seemingly appearing and disappearing within the inkwell.
Color-Shifting Ink
The numeral 100 in the lower right corner on the front of the note changes color from copper to green when the note is tilted. This color shift is readily apparent and difficult to replicate.
Portrait Watermark
When held up to a light, a faint image of Benjamin Franklin can be seen in the blank space to the right of his portrait. This watermark is visible from both sides of the note.
Security Thread
Embedded vertically to the left of Franklin’s portrait is a thread that can be seen when the note is held to light. The thread features the letters “USA” and the numeral “100” in an alternating pattern. It glows pink when illuminated by ultraviolet light.
Additional Features
Beyond the primary security features, the $100 note includes other subtle details contributing to its authenticity.
Raised Printing
The enhanced intaglio printing process gives the portrait of Benjamin Franklin a distinctive texture that can be felt by running a finger across it.
Microprinting
Tiny printed words, such as “THE UNITED STATES OF AMERICA” on Franklin’s collar, are difficult to reproduce with standard printing techniques and require magnification to see clearly.
Federal Reserve and Treasury Seals
A black Federal Reserve System seal is located to the left of the portrait, and a green U.S. Department of the Treasury seal is to the right.
Serial Numbers
Unique serial numbers appear twice on the front of the note.
Older Designs of the $100 Bill
Prior versions of the $100 bill, issued before 2013, had different security features, such as a color-shifting ink that changed from green to black and a simpler security thread. These older notes remain legal tender.
Conclusion
Familiarizing oneself with the security features of the $100 bill is crucial for identifying counterfeit notes. By using a combination of visual and tactile cues, anyone can verify the authenticity of a $100 bill and ensure they are handling genuine U.S. currency. The intricate design and robust security features of the $100 note make it a challenging target for counterfeiters and maintain public trust in U.S. currency.
