Thanks, that's clear. It's interesting there was such a plan. Decimalisation happened before I was old enough to use money but I do remember as a small child asking my dad why they hadn't kept the penny the same and just said from now on, it takes 100 pennies to make a pound, not 240. He said that would have meant a smaller pound, and the pound was the main unit of currency, not the penny. Of course for me as a child, the penny was a real thing (8 of them for the Beano, 2 for a packet of crisps) and the pound was something grown ups had! But this plan shows there had been a third option.
