History of money

The history of money is the development over time of systems for the exchange, storage, and measurement of wealth. Money is a means of fulfilling these functions indirectly and in general rather than directly, as with barter.

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), or be legally exchangeable for something with intrinsic value (representative money), or only have nominal value (fiat money).
