A "quid" is a pound, or a nicker, £1.
Half a dollar is 2/6, or half a crown, or in todays money 12 1/2p
A "tanner" is 6d (sixpence) or in todays money 2 1/2p
The pre 1971(14th February) pound had 240 pennies, or pence, or d. It
had 20 shillings, or 20 bob. 12d made 1s (or 1/-). It sounds very
complicated, and it probably was, but on 14th February 1971 we suddenly
had to get our heads around 100newpence = £1.00, no more pennies,
halfpennies, tanners, 2 bobs, half a crowns, threepenny bits - what a
shock that was!
Interestingly, I was in Kenya earlier this year where their currency is
the Kenyan shilling - which they call the "bob"!
And their 50 shilling coin is exactly the same as our 50p coin!
