50 Things That Made the Modern Economy - Paper Money

A young Venetian merchant named Marco Polo wrote a remarkable book chronicling his travels in China around 750 years ago. The Book of the Marvels of the World was full of strange foreign customs Marco claimed to have seen. One, in particular, was so extraordinary, Mr Polo could barely contain himself: “tell it how I might,” he wrote, “you never would be satisfied that I was keeping within truth and reason”.
