I mean...not much at all. A redesign & print, then just business as usual. It's not like we're going to stop printing hundreds.
Now we're finally killing the penny (yay), and I would even argue hell, let's get rid of the nickel, too. I know there will be a little pain involved, but especially post/mid crazy inflation....my god. WHAT is the purchasing power of a goddamn penny or nickel?? I mean who are we kidding with this nonsense, minting coins with no real value?? Junk.
