Concept:A fiduciary note is a currency note that is not backed by gold but by government securities.
Explanation:Bank notes can be issued against gold reserves or against other acceptable assets.
When a note issue is not fully covered by gold or coin, it is usually backed by government bonds and securities.
Such notes are called fiduciary notes.
They derive their value from the confidence of the public and the promise of the issuing authority to pay.
Fiat money is different: it is money declared as legal tender by the government, but it is not necessarily backed by gold or securities.
Token money and commodity money also do not fit the description.
Therefore, the note that is backed by government securities rather than gold is the fiduciary note.
