Stop making cents: US Mint moves forward with plans to kill the penny

In NL we rounded off before the euro, only had 5, 10 and 25ct coins (and 1 and 2,5 guilder); after the euro came we all of a sudden had more coins (1, 2 , 5, 10, 20, 50) but within a few years collectively stopped using the 1 and 2 cent coins. Don't know who started, but I'm always a bit surprised when I'm in another eu country and get a single cent as change. I mean they eventually add up to something but it takes forever until you could theoretically buy something with it.
