Folks have been collecting paper currency ever since it was invented during the Song Dynasty in China in 960 A.D. Originally intended to be a substitute for Gold and Silver coins, paper money has evolved over the years into “Fiat” currency, backed only by Trust in the issuing government. The result is a wide variety of colorful banknotes, some payable in gold or silver, others payable in nothing and skyrocketing into huge denominations with inflation. We are offering some of the most popular U. S. and Foreign banknotes and currency sheets available on the internet to add to your collection!
