In addition to currency, the concept of total face value is also applied in other fields. For example, in the securities market, the total face value of financial products such as stocks, bonds and funds refers to the product of their total issuance and face value. In the field of bonds, the total face value refers to the total amount of debts undertaken by bond issuers. Total face value is not only a key concept to calculate the value of monetary and financial products, but also an important indicator for investors to understand the market situation and investment risks.
There are some problems needing attention in the calculation of total face value. For example, sometimes some banknotes and coins with smaller denominations may not be included in the total face value due to insufficient circulation, resulting in errors in the total face value of the currency. In addition, the total face value also needs to consider the inflation factor, because with the passage of time, the purchasing power of money will decline, that is to say, the purchasing power of money with the same face value is also declining. Therefore, the total face value, as an index to evaluate the value of money, needs to be revised and adjusted according to the specific situation.
