This volume is a collection of papers on money, currency and economic history. Money and currency have always been used for buying, paying, exchanging values, services or commodities. However there has always been a deep contradiction between the national character of coins and the international trade.0This volume gathers papers on different periods and different regions from Europe to China. These regions were able to trade despite having different cultures, religions, traditions, economic systems. Each country tried to improve trade by developing a new approach with its possible metal stock, social organization or local institutions taken into account. The papers presented in this volume are also the results of debates at recent conferences and meeting with the authors. For this reason they present the state of the art in their fields of research. The aim of this book is to contribute to a diachronic and general analysis of monetary history, as many volumes published in this collection (Collection Moneta) have already done.
