A farthing was a quarter of a penny. So:
4 farthings = 1 penny
12 pennies (pence) = 1 shilling
20 shillings = 1 pound.

The coins were farthing, halfpenny, penny, threepeny bit, sixpence, shilling, two shilling (or florin) and half-crown. Half-a-crown was 2/6d (30 pence, one-eighth of a pound), and the smallest note was 10/- (ten shillings, £0.50).

So there were 240 pennies or 960 farthings in a pound. Then in 1971 it went decimal, and there were 100 new pence in a pound, instead of 240 old ones. I still frequently call 5p coins shillings.
