How did she make her millions? One was born into it. The Queen's Balmoral and Sandringham estates are worth £90 million between them. Her stamp collection, inherited from her grandfather, George V, is worth even more. Then there's £120 million of investment, a £2 million private art collection and her inheritance from the Queen Mother.
The secret of her success? Being Queen. Her bulging coffers are bolstered every year by public funds from the Civil List, to the tune of £9.9 million. That's a handy way to take care of niggly laundry, food and booze bills. Look after the pennies, as they say.
