The 2009 100 Dollar Bill
There are several new design features to the hundred dollar bill, set to be released sometime in early to mid 2011. The most prevalent change in design is the addition of the brown quill and inkwell to the front side. The inkwell features a bell that appears and disappears by changing the viewing angle. The new design also features a borderless Benjamin Franklin and writing from the Declaration of Independence. The United States hundred dollar bill has an average circulation life of approximately 60 months. The size of the bill is 6.14 x 2.61 inches.
The reverse side of the series 2009 100 dollar bill contains a large '100' rotated by 90 degrees on the right side. The new bill includes Rios-Geithner signatures and various other new anti-counterfeiting measures.
1996 Redesign - Released on March 25, 1996
One of the largest changest in the 1996 redesign is the dramatic change in the size and quality of the image of Benjamin Franklin on the front. This redesign contains several new anti-counterfeiting measures, including a watermark of Franklin on the right side and optically variable ink (also known as color-shifting ink) that changes from black to green depending on viewing angle. This redesign also includes several anti-counterfeiting measures carried over from the 1990 design, including microprinting, plastic security thread and red and blue silk fibers woven into the paper. The average life span of a US one hundred dollar bill is approximately 89 months.
The reverse of the 1996 redesign is much more streamlined and clean than the 1990 design, though it still includes Independence Hall. Independence Hall also contains fine line printing as an anti-counterfeiting measure.
1990 Design - First Modern Design with Anti-counterfeiting
The 1990 design was the first to use modern anti-counterfeiting measures, such as the metallic security strip on the left side of the bill and microscopic printing around Benjamin Franklin. The primary purpose for the release of this design was to combat the rampant counterfeiting of the 100 dollar bill during the 1980s. The one hundred dollar bill is one of two US paper notes that does not feature a President, the other bill being the US ten dollar bill. The US one hundred dollar bill has been the largest denomination printed in the United States since 1969.
