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.
