Counterfeit Money

Borders: In real money the borders are nearly perfect

Light- Using light allows you to see the watermarks or security strip, each of which are not usually present in counterfeit money. (Obviously, we were unable to hold these bills to the light)

Color-shifting ink — The newer federal reserve notes in $10, $20 and $50 denominations have color-shifting ink that shifts from copper to green as the note is tilted 45 degrees. The $100 note has a color-shifting “bell in the inkwell.” The $5 note does not have color-shifting ink

3-D security ribbon — The 2004-style $100 notes features a blue ribbon woven into the paper. When you tilt the note forward and backward, the bells and “100s” move side to side. If you tilt the note side to side, they move up and down.

The top bill was counterfeit.

From the image, you can see uneven borders, the ink is not crisp (almost looks faded), and the blue ribbon does not appear to have a 3-D image of a bell.
