The share value stated on a share certificate is called the nominal value. Nominal value, also known as face value or par value, is the minimum amount at which a company's shares can be issued and is typically stated on the share certificate.
The nominal value is a fixed value assigned to the shares when they are first issued and it serves as the legal capital of the company. It is used to calculate the company's share capital and to determine the amount of dividends to be paid to shareholders.
The market value of a share, on the other hand, is the current value of the share in the stock market, which can be higher or lower than the nominal value. The market value is determined by the forces of supply and demand, and can change frequently based on a variety of factors such as the company's financial performance, economic conditions, and investor sentiment.
