“Warhol’s ‘One Dollar Bill (Silver Certificate)’ fetched £20.9m, smashing its pre-sale estimate of £13-18m. This was Warhol’s first such work of a dollar, painted by hand in 1962. A bidding frenzy powered Lucien Freud’s 2002 work ‘Four Eggs on a Plate’, which was originally a gift to the late Duchess of Devonshire, to sell for £989,000, nearly ten times the pre-sale estimate of £100-£150,000.”
