The new $100 bill is scheduled to be the first one with current Treasury Secretary Tim Geitner's (left) signature. But the government will be forced to print the older version with former Bush Treasury Secretary's signature to keep enough bills in circulation.
There are about 6.6 billion $100 bills in circulation at one time so this fiasco accounted for about 1/6 of the total number.
