Is there a 9 dollar bill with obama on it?

No, there is not, at least not in the "real money that you can spend" world. There are, however, commemorative dollars that are sold to collectors, and some companies issue them to honor a president who has been inaugurated. But these dollars are not real coins; they are collectibles. The US Mint has issued actual dollar coins about presidents, but thus far, they have only focused on the founding presidents of our country: Presidents Washington, Adams, Jefferson and Madison.
