@Nicole Sauvage@twitter Actually (Hactually.... if we're going to be posh and all superior like) a shilling was 12 pence, which meant that a pound was in fact 240 pence (being 20 shillings). A crown was 5 shillings, a florin 2 shillings (2 bob-bit), a half-crown was 2 shillings 6 pence. Then there's thruppence, a sixpence (tanner). If someone said "that's 3 and sixpence" It meant it cost 3 shillings and 6 pence = 42 pence.
I hope this clears things up for you ;)
Oh, and we resisted the decimalisation of the currency because it would be too complicated.
and just to round things off: sales of livestock is still in guineas as the 5p (5%) is the auctioners cut - the seller would get the value in pounds.
