Andrew, everyone is welcome, although mainly a UK forum, it doesn't matter. You have a point about the coins lasting longer, but I expect the initial outlay to make the coins is possibly a factor when countries decide how to work it. It must also cost a fair bit to transport coins to be distributed compared to notes, and I think notes should usually last 5+ years, surely. Anyway, i'm sure the governments weigh things up and do whatever is cheapest, unless of course the public completely reject their ideas, like the $1 coin in the US. I can't understand why the richest country in the World has a bank note worth currently less than 60p! Brits, can you imagine having a 50p note!
