From minting coins to digital currencies, Anne McElvoy is joined by Harvard economist Kenneth Rogoff, British Museum coin curator Tom Hockenhull, historian of science Patricia Fara and political economist Ann Pettifor to explore the physical and virtual life of money as we approach the fiftieth anniversary of Decimal Day in the UK. The discussion ranges from the symbolism of images we find stamped on individual coins to the cashless society, and whether or not there is a magic money tree. February 15th 1971 was the date when the old British system of pounds, shilling and pence changed, following earlier unsuccessful attempts and the founding of a Decimal Association in 1841. But what is our relationship with money at the moment in a world of bitcoin, and paying by credit cards not loose change ?

Patricia Fara's books include Life after Gravity: Isaac Newton's London Career; Pandora's Breeches - Women, Science and Power; Science: A Four Thousand Year History Tom Hockenhull is Curator of Modern Money in the Coins and Medals department at the British Museum which was built upon the various collections of Hans Sloane - amongst them were 20,000 coins.
