How do representative and credit money compare to commodity money?

Representative and credit money differ from commodity money primarily in their intrinsic value and backing. Commodity money has intrinsic value, as it is made from a physical commodity (like gold or silver) that holds value on its own. In contrast, representative money is backed by a promise to exchange it for a commodity, while credit money, like banknotes or digital currency, derives value from trust in the issuing authority rather than any physical commodity. Both representative and credit money facilitate transactions more efficiently than commodity money by not requiring the direct exchange of physical goods.
