They should make it work on the 'old money' system of penny, shilling and pound, with twelve pence to a shilling and twenty shillings to the pound, then use the abbreviation 'd' for pence, and then throw in farthings (quarter penny) and half-crowns (two shillings and six pence) because if there's one thing I've learnt about finance, its that the more confusing things are, the easier it is to make a profit.
