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.
They’re not made from copper in Europe though.
I actually looked it up. They are 5,65% copper, the rest ist iron. But because they are not 100% copper, they are less valuable then 1 cent. https://de.m.wikipedia.org/wiki/Euromünzen
