> a fine of three pounds, six shillings, and eight pence This is exactly 3 1/3 pounds. > one pound, ten shillings, and four pence Exactly 1 and 31/60 pounds, or 30 and 1/3 shillings. > thirteen shillings and four pence Exactly 13 and 1/3 shillings, or 160 pence, which is 2/3 of a pound. I suppose they liked the number repetitions. And when you're dealing with such small divisions of a very valuable currency, "rounding up" to the nearest pound could be considered extremely punitive. It'd be like going from a fine of $51000 to $60000 just to make the number round.
