Do Old $100 Bills Have Watermarks?

In 1996, the $100 bill was significantly redesigned. New security features included a watermark of Benjamin Franklin that can be seen on both sides when held up to the light, ink that changes colors when seen from different angles and advanced microprinting. In 2013, further security enhancements were made, such as an increased use of color, raised printing and a 3D security ribbon. Color-shifting ink is used on the number in the lower right corner of the front side.
