For those handling 100€ and 200€ notes… new ones are on the way…
As I understand it… 500€ notes are no longer being issued… there’s enough in circulation…

Apparently the main use for the €500 note was by criminals to move large volumes of cash around.
In this day and age there is no great need for anything above €50
