That's more like the US $100, which is not accepted usually because

- they are a high denomination bill and people who attempt to counterfeit money like to copy those

- they are not encountered often, and so staff can be unfamiliar with how to verify their authenticity

- as the highest denomination US note, it is very hard to get it out of your till and back as change, and meanwhile it has probably taken a bunch of bills you do often need to give back out of the till

Your bank will take it at least. Not so with a 500 EUR note even in Europe.

If the bank doesn't take it, how do 500EUR notes even wind up in circulation then?
