His portrait on the $100 bill serves as a reminder of his important role in shaping America’s history. 

Additional Imagery and Text

In addition to Benjamin Franklin’s portrait, the front of the $100 bill also includes various additional imagery and text. One notable feature is the watermark of Franklin’s face, which can be seen when holding the bill up to the light.

The intricate designs and color patterns make it more difficult to reproduce the bill accurately, aiding in its authenticity.

Back of the $100 Bill

The back of the $100 bill is just as fascinating as its front. Let’s take a closer look at the design elements that make the back of this iconic bill so unique and special.

Independence Hall

One of the prominent features on the back of the $100 bill is a striking image of Independence Hall. Located in Philadelphia, Pennsylvania, Independence Hall holds immense historical significance as the birthplace of the United States.

It was here that both the Declaration of Independence and the United States Constitution were debated and adopted. The inclusion of Independence Hall on the $100 bill serves as a reminder of the country’s rich history and the principles upon which it was founded.

Another captivating element on the back of the $100 bill is the depiction of the Great Seal of the United States. This seal consists of a bald eagle with its wings spread wide, clutching an olive branch in one talon and a bundle of arrows in the other.

The eagle represents the strength and resilience of the nation, while the olive branch symbolizes peace and the arrows symbolize the country’s ability to defend itself. The Great Seal is a powerful symbol of American unity and patriotism, making it a fitting addition to the $100 bill.

Understanding the design elements on the back of the $100 bill not only provides insight into the history and symbolism of the United States but also allows us to appreciate the thought and craftsmanship that goes into creating these iconic pieces of currency.

Security Features

When it comes to the $100 bill, security features are of utmost importance to prevent counterfeiting and ensure its authenticity. The United States Treasury has implemented several advanced security measures that make the bill incredibly difficult to replicate.

Let’s take a detailed look at some of the security features that protect the front and back of the $100 bill.

Advanced Printing Techniques

The $100 bill is printed using advanced techniques that make it nearly impossible to reproduce accurately. The printing process involves a combination of intaglio, offset, and letterpress printing, creating intricate details that are difficult to replicate.

This intricate printing process is one of the reasons why counterfeiters find it challenging to produce convincing fake $100 bills.

Color-Shifting Ink

One of the most recognizable security features of the $100 bill is the color-shifting ink used on the numeral 100 in the lower right corner of the front of the bill. When you tilt the bill, the color of the numeral shifts from copper to green.

This unique feature is difficult to reproduce and serves as a quick and simple way to verify the authenticity of the bill.


The $100 bill incorporates watermarks into its design as an additional security measure. When you hold the bill up to the light, you can see a faint image of Benjamin Franklin on the right side. This watermark is embedded into the paper itself, making it extremely difficult for counterfeiters to replicate.

Security Thread

The $100 bill features a thin, embedded security thread running vertically down the bill. The thread glows pink when exposed to ultraviolet light, further confirming its authenticity. Additionally, the thread is woven into the paper, making it difficult to remove or replicate without damaging the bill.


Microprinting is another security feature found on the $100 bill. Tiny text, so small that it appears as a solid line to the naked eye, is scattered throughout the bill. These lines contain phrases such as “USA 100” and “The United States of America.”

Counterfeiters struggle to reproduce this level of detail, making microprinting an effective security measure.

Serial Numbers

Each $100 bill has a unique serial number printed in two locations – one on the front and one on the back. These serial numbers help track the bill’s circulation and make it easier to identify counterfeit bills.

By comparing the serial numbers against a database maintained by the Treasury, banks, and businesses can quickly detect fake bills.
