I know they had a vanity plate for the bills a long time ago because my grandfather had it on his car (probably 25-30 years ago they came out).
This is what it looked like.
I don't know if they stopped doing it or if they were still available but either way, this is an updated version.
What I didn't know was the DMV offers a bunch of different custom plates already other than the 2-3 that they allow you to pick as the standard plates.
