Pound sterling

The Pound Sterling was a form of currency used in the United Kingdom through at least the early 21st century. It was one of the oldest currencies in continuous use. A slang term for a pound was 'quid'. (DW: Rose)

Until 1971, the pound was subdivided using a system of 20 shillings to a pound, and 12 pennies to a shilling. (DW: Remembrance of the Daleks)

Susan Foreman caught the attention of her teachers because of her inability to remember how many shillings were in a pound when she and the First Doctor settled down in 1963 London. She erroneously believed that Great Britain had switched to the decimalised Pound, something that would not occur until until 1971. (DW: An Unearthly Child)

Around the late 20th century or early 21st century Britain introduced a five pound coin. (DW: Battlefield).

The Third Doctor and Sarah Jane once discovered that they were in a Parallel universe because £5 notes had a picture of Edward IX. (PHS: Who's Who?)

By 2050 the UK was no longer using this currency, having switched to Credits (K9TV: Oroborus)
