This fall, the Federal Reserve will be releasing a new $100 bill. The new bills will be more colorful, more secure and harder to replicate.

Some of the new changes include a hologram-type 3D security ribbon. It will have bell icons that turn into 100s when you tilt/move the bill.

Another cool change is that the bell on the bill changes from copper to green when moved.

Pretty cool stuff to look forward to.  Time to start saving the old ones if you are a collector.
