for bonds, it is the amount paid to the holder at maturity. Also known as par value or simply par.
For an equity share, the face value is usually a very small amount (Rs. 5, Rs. 10) and which may quoted higher in the market, at Rs. 100 or Rs. 1000 or any
other price.
For a debt security, face value is the amount repaid to the investor when the bond matures (usually, Government securities and
corporate bonds have a face value of Rs. 100). The price at which the security trades depends on the fluctuations in the interest rates in the economy.
