Representative money is any medium of exchange that represents something of value, but has little or no value of its own (intrinsic value). However, unlike some forms of fiat money (which may not have anything of value backing it), to be a genuine representative money, there must always be something valuable supporting the face value represented.<ref name=mundell/>
More specifically, the term representative money has been used variously to mean:
- A claim on a commodity, for example gold certificates or silver certificates.<ref name="mundell">Robert A.

- Any type of money that has face value greater than its value as material substance. Used in this sense, most types of fiat money are a type of representative money.<ref>Template:Cite book</ref>
Historically, the use of representative money predates the invention of coinage. In the ancient empires of Egypt, Babylon, India and China, the temples and palaces often had commodity warehouses which issued certificates of deposit as evidence of a claim upon a portion of the goods stored in the warehouses, a form of "representative money".<ref name=mundell/>
According to economist William Stanley Jevons (1875), representative money in the form of bank notes arose because metal coins often were "variously clipped or depreciated" during use, but using representations for the value stored in banks ensured its worth. He noted that paper and other materials have been used as representative money.<ref>William Stanley Jevons, Money and the Mechanism of Exchange, Chapter XVI, "Representative Money"</ref>
In 1895 economist Joseph Shield Nicholson wrote that credit expansion and contraction was in fact the expansion and contractions of representative money.<ref>Joseph Shield Nicholson, A treatise on money and essays on monetary problems], Chapter VI, Effects of Credit or "Representative Money" on prices, pp. 72–74, A. and C. Black, 1895.</ref>
In 1934 economist William Howard Steiner wrote that the term was used "at one time to signify that a certain amount of bullion was stored in the Treasury while the equivalent paper in circulation" represented the bullion.<ref name="p.30"/>
