pounds sterling
I was making a hotel booking recently and got stumped by the currency converter for a while. The UK currency was listed in the alphabetical list as ‘pounds sterling’.
Whilst technically correct, UK pound or British pound are more normal in these lists, giving precedence to the country name rather than the currency name. With most countries that makes finding the relevant currency easy but it is still a bit tricky when dealing with the UK as you never know whether it’ll be listed under U or B.
So it would help not to throw P into the mix as well.
