That's not the reason for changing it, security is. It's far too easy to counterfeit US currency. There are a huge variety of considerations when it comes to bother paper currency and coin. For example, if the notes are of different sizes, then a blind person can tell how much cash they're handling.

I like the new Australian plastic money. Doesn't get ruined in the washing machine, and the transparent windows with holograms haven't (yet) been counterfeited (so they say...)
