I live in the Eurozone. We had 1 and 2 cent coins for a while. Where I live these were quickly deprecated and I think in most other Eurozone countries too by now.
I have thrown any of these coins straight in the bin soon as somebody gave them. Too much hassle and requires too big a wallet to drag along, for literally pennies.
When I first realized dealing with coins was inversely proportional to their denomination I threw out less than a Euros worth.
I do not understand anyone who doesn't throw out their pennies.
