Historically, precious metals such as gold and silver were gradually fixed as currency because of their small size, high value, easy division, easy wear and tear, and easy storage and carrying, so the currency at that time was called currency.

Later, due to the low production cost of paper money, it is easier to keep, carry and transport, which can avoid the wear and tear of metal money in circulation. Paper money has gradually replaced metal money, but we still retain the title of "money".
