Book excerpt: This book, first published in 1949, is the original and key survey of the stages which preceded the use of coins as the medium of exchange, and of the objects that coins displaced, objects which for want of a better name are here called primitive money. It examines in detail the primitive monies of the world, monies from far in the distant past, and monies still in use today. It is the essential reference source on the many different objects used as currency.
