How to spot fake bills that are possibly being passed in Western Washington

The Seattle Secret Service office gets about $1 million in counterfeit bills every year.

If you're suspicious of a bill, hold it up to the light and look for:

  • A security thread on the left side.
  • You should a watermark: a ghostly image of the bill's portrait on the right side
  • Color -shifting ink: Tilt the note to see the numeral 20 or 100 in the lower right corner of the note shift from copper to green.
