Can Gold Be Used as a Currency?

By GovMint :

Gold can indeed be used as a currency, though its role in everyday transactions is limited in modern times. Historically, gold has been a fundamental part of monetary systems due to its intrinsic appeal and relative scarcity. Today, many gold coins carry face value, but like silver coins, their precious metal content alone, much less any numismatic factors such as design, mintages, and special finishes, make it impractical to spend gold coins during everyday transactions even though in some cases you technically could.
