FED to distribute new $100 bills in October.

The Federal Reserve Board announced that the redesigned $100 note, originally unveiled in 2010, will begin circulating on Oct. 8.
The Fed said the note, which incorporates a blue, 3-D security ribbon, will be easier for the public to authenticate but more difficult for counterfeiters to replicate.

New features to the bill’s design include raised printing, a color-shifting bell in the copper inkwell that changes colors from copper to green, a color-shifting numeral 100 on the front of the bill, a large gold numeral 100 on the back of the note, and small printed words that appear on Benjamin Franklin’s jacket collar, around the blank space containing the portrait watermark, along the golden quill and in the note borders.
