How many pennies were in a British pre-decimal pound?
After the Norman Conquest in 1066, the pound was divided into twenty shillings or 240 pennies. It remained so until decimalization on 15 February 1971.
There were twenty (20) shillings per pound.
The shilling was subdivided into twelve (12) pennies.
The penny was further sub-divided into two halfpennies or four farthings (quarter pennies).
2 farthings = 1 halfpenny
2 halfpence = 1 penny (1d)
3 pence = 1 thruppence (3d)
6 pence = 1 sixpence (a 'tanner') (6d)
12 pence = 1 shilling (a bob) (1s)
2 shillings = 1 florin ( a 'two bob bit') (2s)
2 shillings and 6 pence = 1 half crown (2s 6d)
5 shillings = 1 Crown (5s)
