"Australian Money Slang
Decimal currency, Dollars and Cents, was introduced into Australia February 14th. 1966, so many Australian don't know about the old currency or the slang terms used.
The old imperial currency was known as LSD, no not the drug, but Pounds Shillings and Pence. The symbol for Pounds is £, not unlike the letter "L", Shillings was S, and for some reason Pence was represented by the letter "d", hence LSD.
There was also a rich slang for the old currency:-
trey - three pence
zack - sixpence
deener, deenah or bob - schilling
two bob - two shilling or a florin, and
quid - pound.
There seemed to be no slang for a penny, or a farthing, 1/4 penny, but a 1/2 penny was pronounced "hapenny".
For some reason there is no slang for the current decimal currency, except perhaps the American "buck" for dollar, although not used very widely."
A schilling or a bob was sort of like 10 cents, with 2 bob being a florin or 20 cents. Sixpence was sort of like 5 cents.
