Gold is also easily transportable, as it has a high value-to-weight ratio compared to other commodities such as silver. It is fungible, with a low spread between the prices to buy and sell. Gold has been used as money for many reasons. The gold reserves of central banks are dominated by gold bars, but gold coins may occasionally contribute. For example, the American Gold Eagle has a denomination of 10 USD, but a metal value of more than $800 USD (being around a half an ounce). While modern gold coins are still legal tender, they are not observed in everyday financial transactions, as the metal value normally exceeds the nominal value.

Alloyed gold coins, like the American Gold Eagle and South African Krugerrand, are typically 91.7% gold by weight, with the remainder being silver and copper.
