They’re not worth anything, never were but even less through the years with inflation.
If a store wants to sell something for 99 cent, they can either just take 1€ or 95 cent.
Maybe even 5 cent pieces? But that would be a bit radical.
I am a bit annoyed that easy ideas like this are never discussed in politics, or wherever. It would make our lives just a little bit easier, and having them achieves NOTHING.
I’ve been there a lot, so I know the situation. There are quite a few things that are odd and inconvenient over there. But worst of all is the Autobahn. Not having a speed limit makes it a terrible place to drive. And generally their addiction to cars and their aversion to working, affordable public transport.
