The $100 bill will once again get a redesign to add even more security. A couple of weeks ago I got $100 bill from the bank. When I tried to use it the retail store didn't accept it as it didn't have the security strip. Apparently the Benjamin was a $1980's bill which lacked any of the security features of today. Starting Oct 8th you will see a new $100 that adds blue, 3-D security ribbon and a disappearing Liberty Bell in an inkwell.
