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.&lt;p&gt;There&amp;#x27;s also enduring slang for some some values of cash, that doesn&amp;#x27;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,.</text><parent_chain></parent_chain></comment><story><title>Understanding British Money: What&apos;s a Quid?
