Description : If metal is so cumbersome why should we not have only paper money why should we not print as much of it as possible?
Last Answer : Paper is lighter than metal, it also saves use of silver and other metals when they are scarce. Perhaps you may ask "Then why not have paper money only?" The answer is, it would be impossible ... the right amount of paper money that would keep prices at their proper natural level.Hope it helps!!!
