Slang terms for old money
I went into a shop for half a pound of PG Tips. The shop assistant said "that'll be half a dollar". I looked in my pocket and found one bob, two tanners and two joeys. I had just enough.
In the pre-decimal era half a dollar was half a crown, a bob was a shilling, a tanner a sixpence and a joey a threepenny bit.
These are a few of the most common slang terms for pre-decimal coins:
- Coppers - farthing, halfpenny, penny coins
- Joey - 3d or threepence
- Tanner - 6d or sixpence
- Bob - one shilling
- Half a dollar - half a crown
- Dollar - five shillings
Joey for threepence
George Orwell used the term 'Joey' in 'Keep the Aspidistra Flying'. At the beginning of chapter one, Gordon Comstock contemplates his last fivepence halfpenny - one 'Joey', two pennies and a halfpenny.
The original nickname 'Joey' was for a groat, worth fourpence. But since the groat disappeared the name transferred to the silver threepence.
'Joey' is after Tory MP, Joseph Hume. He campaigned for the re-introduction of the groat, because he was tired of London cabbies saying they hadn't change for a sixpence and keeping the change as a tip. Now the customer could give the cabby a groat worth only four pence. The cabbies took their revenge by calling the groat a 'Joey'.
Bob for shilling
The term bob for shilling goes back to the 1700s, but its origin is unclear.
Tanner for sixpence
The most likely explanation is that it comes from John Sigismund Tanner. He was the engraver at the Royal Mint who designed the sixpence for the reign of George II. Although the first sixpences dates from 1551 in the reign of Edward VI.
Dollar for five shillings
The origin of the term 'dollar' for five shillings goes back to the late 1700s. The Royal Mint had a shortage of silver. To keep enough money in circulation, the UK imported Spanish eight-real pieces (pieces of eight) which were also known as Spanish Dollars. The Mint over stamped them with a portrait of George III and issued them with a value of 4s 9d (their bullion value). The Mint later revalued them to five shillings. Spanish dollars were then over stamped with a new design and called 'Bank of England dollars'. 
The original US dollar was based on the Spanish dollar. It was the same size and weight and also worth five shillings.
In the twentieth century five shilling pieces, known as crowns, were for commemorative issues only. But the term 'dollar' for five shillings continued. A half crown was worth 2s 6d. It became a half dollar. For comparison, a US dollar was worth 7s 2d in 1964. (See Foreign currency in the 1960s).
A few more archaic terms are:
- Brown - halfpenny or penny
- Tizzy - sixpence
- Thin - sixpence
- Half bull - half a crown
- Bull - crown
- Quidlet instead of quid - one pound
- Canary - sovereign
Terms for amounts in pounds
- Quid - one pound
- Nicker - one pound
- Fiver - five pounds
- Tenner - ten pounds
- Score - twenty pounds
- Pony - twenty-five pounds
- Monkey - five hundred pounds
- Grand - one thousand pounds
Most of these are well known today. The terms 'monkey' and 'pony' were less well known in the 60s. An article in the Daily Express explained them as 'racing slang'. The author relayed a story of a punter who telephoned his bookmaker to place a bet of a monkey each way on a horse thinking the term meant twenty-five pounds. Only to find out he had won a fortune when the horse finished first. The bookmaker sent him a complimentary ticket to London Zoo, so that he could learn the difference between a monkey and a pony.
