I don't know but I guess they still would have to accept them since they are still official currency.

I used to live in Finland for two years. The shop close by to my home wouldn't accept 1 or 2 cents so I just put them in a drawer and never worried about it again. Don't know if they are obliged to accept them.

Finland: Price totals are rounded to 5 cents at the checkout but the smaller money is valid and you can generally use them, unless a shop specifically informs that they don't accept them.

I'm from Italy, most machines that take cash straight up don't accept 1 and 2 cent coins and 500€ notes anymore, they'll just spit them out. I don't think I've ever paid a cashier with those, so I don't know what the policy is, but I think they are allowed to refuse them. It's still legal tender so banks will take them; I have a big jar at home where I collect all the small cents, I plan to take it to a bank once it's full and see what I can buy with it (stonks). I can tell you that if you make an electronic payment you will pay the exact price, but if you're paying in cash it will be rounded to the nearest .05.
