Why can't we get rid of 1p, 2p, 5p coins?

I'd start one if I were you.

Your mum, dad and granny will sign. Maybe that odd couple who live across the road would too. You know, the ones who are always complaining and have problems with everything. And you could ask the nurse when she comes to give you your injections. That would make six.

I mean there's no point in having them at all. They got rid of 0.5p coins decades ago.

One word, "Competition".
