There are also coins called the Sovereign and Britannia, which are both legal tender, although not in general circulation. Both are minted from 24 carat gold. The Sovereign has a face value of 1 pound and I think the Britannia has a face value of 5. There actual value, on gold markets, is hundreds of pounds, and for a Britannia is over a thousand. Because they are legal tender, and could theoretically be used to buy a bottle of milk, they are exempt from VAT and capital gains tax, when buying or selling.
There's also enduring slang for some some values of cash, that doesn't necessarily have an accompanying bank note. A Pony for 25 pounds and a Ton for 100 is still fairly widely understood, but mostly heard these days in Guy Ritchie movies,.
