Easiest Dollar to Counterfeit and 6 Ways of Spotting Counterfeit Money

5. Color Shifting Ink

We move on to visual clues. Color shifting ink is exactly what the name implies, ink that changes color under different angles of light. While not impossible to replicate on fake notes, it is both hard and expensive and requires high-end equipment. This method of spotting counterfeit money is easy to use and pretty reliable. Just hold the note under a light source and twist it around. If denomination in the lower right corner changes color (in cases of the twenties from copper to green), it is probably a real deal. If not, don’t take the bill.
