The most current release of the US $20 bill began rotation on October
9, 2003. Jackson's blown up head and the shiny ink of the "20"
may be familiar images of the recently departed 1998 US $20 bill; however,
one aspect of our new $20 is strikingly different. Colors. Never before
witnessed in contemporary American history has colors other than black
and green been used in US cash currency. Soft hints of peach
and blue can be seen on both sides of the bill, color-shifting
ink of the "20", and little yellow
20's are on the back.
The use of colors in the new US $20 wasn't solely implemented just
to make our money cuter. In fact, it's just one of the new security
features devised to deter the manufacturing of counterfeit US $20 bills.
Some other features are the watermark
(a ghostly image of Jackson's head) and the security
thread (the blur next to "USA
TWENTY" is supposed to be a flag).
