Yes, there is a new 100 dollar bill that was introduced by the Federal Reserve on October 8, 2013. The new bill has several security features that make it more difficult to counterfeit, including a 3D security ribbon, a color-changing bell in the inkwell, and a watermark that is visible when the bill is held up to the light.

The new 100 dollar bill also features a portrait of Benjamin Franklin on the front, and an image of Independence Hall on the back. The design of the bill was updated to incorporate new security features and to make it more visually appealing. The overall color scheme of the bill has been changed, with more blue and less green than the previous version.
One of the most prominent new security features on the bill is the 3D security ribbon, which is located to the right of the portrait of Benjamin Franklin. The ribbon is made up of thousands of tiny lenses that create a shifting image of bells and the number 100 as the bill is tilted back and forth. The ribbon is designed to be extremely difficult to replicate, making it a key feature in preventing counterfeiting.
Another new security feature on the bill is the color-changing bell in the inkwell. When the bill is tilted, the bell changes color from copper to green, adding another layer of security. This feature is located to the right of the portrait of Benjamin Franklin, just below the 3D security ribbon.
The new 100 dollar bill also includes a watermark that is visible when the bill is held up to the light. The watermark features an image of Benjamin Franklin and the words “USA 100” on the right side of the bill. This feature is designed to be difficult to reproduce, as it requires specialized equipment and materials.
In addition to these new security features, the design of the bill has been updated to make it more visually appealing. The overall color scheme of the bill has been changed, with more blue and less green than the previous version. The portrait of Benjamin Franklin has been moved to the left side of the bill, and the image of Independence Hall on the back has been updated to include more detail.
The new 100 dollar bill is part of an ongoing effort by the Federal Reserve to update the designs of US currency and to incorporate new security features. The previous version of the 100 dollar bill had been in circulation since 1996, and was in need of an update to address concerns about counterfeiting.
Overall, the new 100 dollar bill is a significant improvement over the previous version in terms of both security and design. The new security features make it more difficult to counterfeit, while the updated design makes it more visually appealing. As the Federal Reserve continues to update the designs of US currency, we can expect to see more improvements in the years to come.
