It's happened more than once that people thought $2 bills were fake; here's a recent example: https://www.nbcdfw.com/news/local/houston-school-confuses-2-...

I had someone pocket a Susan B. Anthony $1 coin and put their own money in the register to replace it, but that was because it was a rare coin, not because they thought it was fake.

I love Wozniak’s story about $2 bills that are particularly difficult to believe in reality of: https://web.archive.org/web/20111122202554/https://archive.w...

That is way beyond my usual experience with the bills! XD

Lol, lost it at the "Laser Safety Officer" fake id... :'D

$2 bills aren’t rare at all. You can walk into your local bank and get a stack of them anytime, if you’d like.

Okay, awesome point.

Meanwhile, in my 25 years of living in the US (NJ, SoCal, and NorCal), I can count on one hand the number of times I've come across them "in the wild".

I started collecting them in 2004 by keeping every one I ran into in person and I now have: 3.

They’re mostly used by strip clubs so if that’s not your thing, you’ll rarely see them.

Strip clubs also commonly use 2 dollar bills.

The Venn diagram of things I learn on HN and things I expected to learn on HN has an ever decreasing intersection.
