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.
Ah those arguments have already been done to death in the countries that did implement it. It really doesn’t change a thing in the grand scheme of things. Even the shops were worried that they’d lose money on it, so no, it’s not a money making scheme, it averages out perfectly fine.
