Hold the note to light and look for a faint image of Benjamin Franklin in the blank space to the right of the portrait. The image is visible from both sides of the note.
Tilt the note to see the numeral 100 in the lower right corner of the front of the note shift from copper to green.
Move your finger up and down Benjamin Franklin’s shoulder on the left side of the note. It should feel rough to the touch, a result of the enhanced intaglio printing process used to create the image. Traditional raised printing can be felt throughout the $100 note, and gives genuine Federal Reserve notes their distinctive texture.
A large gold numeral 100 on the back of the note helps those with visual impairments distinguish the denomination.
Look carefully (magnification may be necessary) to see the small printed text THE UNITED STATES OF AMERICA on Benjamin Franklin’s jacket collar, USA 100 around the blank space containing the portrait watermark, ONE HUNDRED USA along the golden quill, and small 100s in the note borders.
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.
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.
