Quotations: "My interest in the history of money began at five years old when I unearthed some ancient Roman coins in a wood near my primary school. I’ve been pursuing monetary economics for over half a century, as teacher and writer, only to be overtaken finally by "e-money". Money never loses its shine — in theory or practice. It talks all languages and to all ages. To me it mostly says "goodbye"."
