Respectfully, it's no surprise that all the fake bills you saw looked fake to you. This is similar to the attitude I frequently see from law enforcement about how all criminals eventually get caught. Ultimately, it's impossible to know how good your test is for determining X if you have no ability to cross-check yourself.

This idea is often called the "Toupée fallacy", the idea being people often think all hair toupées look fake because they can always spot them, implicitly ignoring that they are not accounting for the fact that some could be good enough that they are unable to spot them.

  Except that this effect mysteriously didn't happen with fake 20 dollar bills! Perhaps we have a fallacy fallacy on our hands.

  Well, not entirely, because we also had very expensive machines that ID fakes. We used this when one was suspicious but weren't sure. I dont know how it worked, but it had more sensors and a process of ID'ing bills that I still don't really understand. This is more often then not how we found 20's since usually they were too numerous to scrutinize manually. So you could try and walk in with a great toupee but I'm gonna suck it off with my expensive vacuum anyway.

    This is only a counterargument if you actually put all of the bills through this machine, eventually. Did you do that, perhaps as a final sorting measure? Otherwise, the ones that were too good to arouse your suspicion were swept through.

      Well, eventually all of our money would be sold to this machine. So, yes. Our drawers were only allowed to have some small sum, and usually no large bills.

Well we did. I explained it below if you want to read. But we had a very expensive machine that sorted, scanned, ID'd and stored bills for us. This was our cross-check. I could spot it with our blacklights, back lights, touch - just to double check, I would stick it through the machine and it would spit the bill back to me.
