I must admit that in the 9 or so months I have been in the Netherlands, I have never seen a 1 euro cent piece, much less used one.
But a few days ago I found one:
It was actually in my wallet, of all places. I guess I was given it as change. It’s quite possible that I received it while I was in Dublin’s airport waiting for the flight home. It’s actually quite tiny – much smaller than the euro 5 cent piece.
But I’ve never seen it in use in the Netherlands. I’ve seen a few signs saying that it isn’t accepted at certain stores, but that’s the only reference to it. The reason the 1 cent piece isn’t used here is because when you pay with cash, the prices are rounded up or down to the nearest 5 cents. If you use your debit card, then you pay the exact price.
