Re: Hooray for Avoirdupois and pounds, shillings and pence
Auvoirdepois has nothing to do with pounds, shillings and pence. Precious metals are measure using the Troy system that has 20 ounces to the pound. That is why a pound of gold weighs more than a pound of feathers. 1GBP was originally worth a pound of gold hence 20 shillings to the pound.
