$100 Note (2013-Present)
In its first redesign since 1996, the new-design $100 note features additional security features including a 3-D Security Ribbon and color-shifting Bell in the Inkwell. The new-design $100 note also includes a portrait watermark of Benjamin Franklin that is visible from both sides of the note when held to light.、
Security Thread
Hold the note to light to see an embedded thread running vertically to the left of the portrait. The thread is imprinted with the letters USA and the numeral 100 in an alternating pattern and is visible from both sides of the note. The thread glows pink when illuminated by ultraviolet light.
Bell in the Inkwell
Tilt the note to see the color-shifting bell in the copper inkwell change from copper to green, an effect which makes the bell seem to appear and disappear within the inkwell.
Color-Shifting Ink
Tilt the note to see the numeral 100 in the lower right corner of the front of the note shift from copper to green.

The $100 note features additional security features including a 3-D Security Ribbon and color-shifting Bell in the Inkwell.
3-D Security Ribbon
Tilt the note back and forth while focusing on the blue ribbon. You will see the bells change to 100s as they move. When you tilt the note back and forth, the bells and 100s move side to side. If you tilt it side to side, they move up and down. The ribbon is woven into the paper, not printed on it.
