Silver and gold belong to money, right?

Money is the medium of commodity exchange.

At present, there are four main forms of money: physical money, metal money, credit money and electronic money.

Physical currency is shells, salt, slaves, livestock and so on used in ancient times.

Metal currency includes gold, silver and copper.

Credit currency is the paper money we use now.

Electronic money is our current virtual money, such as the numbers used in online transactions.

The gold and silver mentioned by the landlord are the main currencies used by human beings. Today, gold and silver can no longer be used as the main form of money, but they can be stored as a way to preserve value. Therefore, the landlord's question can not be simply answered yes or no, but should be said under what circumstances.
