£5 Kingfisher, £10 Fox, £20 Bottlenose Dolphin, £50 Eagle.
Get rid of copper coins and the 20p (replaced by a 25p) coin while we’re at it.
May as well have a £100 (Pine Marten) note while we’re at it.
Edit: bring back £1 notes (pigeon) too. Feck coins.
....a while ago I stumbled on this video by Matt Parker (who does maths based silliness), where he proposes to ditch the £2 coin for a £1.75 coin after he'd done the maths to work out optimal number of fewest coins that would be needed to pay a range of change
