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.
We haven’t had 1 and 2 cent coins in YEARS. If something is €19,99, you have to pay €20 for it if you use cash. But if you use a card or mobile payment, it’s only €19,99. So the prices are rounded to 5 cents but only if you pay using cash.
