From Wikipedia, the free encyclopedia

The history of money concerns the development throughout time of systems that provide the functions of money. Such systems can be understood as means of trading wealth indirectly; not directly as with bartering. Money is a mechanism that facilitates this process.

Money may take a physical form as in coins and notes, or may exist as a written or electronic account. It may have intrinsic value (commodity money), be legally exchangeable for something with intrinsic value (representative money), or only have nominal value (fiat money).
