Thanks for all your comments folks..........some of you are showing your age more than others.......I am, of course, far too young to remember
For the youngsters:
"Before the 15 February 1971, there were twenty shillings to the pound.
The shilling was twelve pennies.
The penny was divided into two halfpennies or four farthings..........
2 farthings = 1 halfpenny
2 halfpence = 1 penny
3 pence = thruppence
6 pence = sixpence (also called a tanner)
12 pence = 1 shilling (also called a bob)
2 shillings = florin
2 shillings and 6 pence = a half crown
5 shillings = a Crown "
