has anyone gotten one of these yet? it is WAAAY complicated! check out the features! Click here to see that bad boy! *Security Thread* Hold the bill up to the light and look for the security thread, or plastic strip, that is embedded in the paper and runs vertically up one side of the note. If you look closely, the words "USA TWENTY" and a small flag are visible along the thread from both sides of the note. This thread glows green when held under an ultraviolet light. *Watermark* Hold the bill up to the light and look for the watermark, or faint image, similar to the portrait on the face of the note. The watermark is part of the paper itself and can be seen from both sides of the note. *Color-shifting Ink* Look at the number "20" in the lower right corner on the face of the note. When you tilt the note up and down the color-shifting ink changes color from copper to green and back again. cool yeah?
