The U.S. government might be shut down, but the Federal Reserve is having no trouble keeping busy. Tuesday, the system will begin circulating new $100 bills.
The notes will still largely resemble the old ones -- green in color with Benjamin Franklin's face displayed across its center -- but will come with several new security features, including a 3-D security ribbon and a bell that changes colors.

The bills will also be engraved with new ink and will bear a unique texture due to raised printing. Government officials say consumers may not see the notes in the beginning stages of circulation, but will increasingly as financial institutions order more $100s.
