Symbolic money is a form of money that is more valuable than its intrinsic value. Initially, banks issued coins that were worth their weight in gold or other precious metals, but soon banks began issuing token money such as banknotes or coins that they could guarantee to be worth a certain amount of precious metals. Token money relies on a bank guarantee or the backing of banknotes or coins and relies on government laws or regulations. In some cases, the value of tokens can go down due to inflation or because the government is printing too much money.
