The face value is the value of a coin, stamp or paper money, as printed on the coin, stamp or bill itself by the issuing authority.
 The face value of coins, stamps, or bill is usually its legal value.
 However, their market value need not bear any relationship to the face value.
 For example, some rare coins or stamps may be traded at prices considerably above their face value.
Revaluation is a change in a price of a good or product, or especially of a currency, in which case it is specifically an official rise of the value of the currency in relation to a foreign currency in a fixed exchange rate system.
 Under floating exchange rates, by contrast, a rise in a currency's value is an appreciation.
 Altering the face value of a currency without changing its purchasing power is a redenomination, not a revaluation (this is typically accomplished by issuing a new currency with a different, usually lower, face value and a different, usually higher, exchange rate while leaving the old currency unchanged; then the new replaces the old).
A zero-coupon bond (also discount bond or deep discount bond) is a bond bought at a price lower than its face value, with the face value repaid at the time of maturity.
 Note that this definition assumes a positive time value of money.
 It does not make periodic interest payments, or have so-called "coupons", hence the term zero-coupon bond.
 When the bond reaches maturity, its investor receives its par (or face) value.
 Examples of zero-coupon bonds include U.S. Treasury bills, U.S. savings bonds, long-term zero-coupon bonds, and any type of coupon bond that has been stripped of its coupons.
The half sovereign is an English and British gold coin with a face value half that of a sovereign: equivalent to half a pound sterling, ten shillings, or 120 old pence.
 Since the end of the gold standard, it has been issued only in limited quantities as a commemorative coin with a sale price and resale value far in excess of its face value.
 The main reason for this is because they are used, along with other coins of this type as bullion coins.

".

Coin debasement is the act of decreasing the amount of precious metal in a coin, while continuing to circulate it at face value.
 This was frequently done by governments in order to inflate the amount of currency in circulation; typically, some of the precious metal was replaced by a cheaper metal when the coin was minted.
 But when done by an individual, precious metal was physically removed from the coin, which could then be passed on at the original face value, leaving the debaser with a profit.
 Coin debasement was effected by several methods, including clipping (shaving metal from the coin's circumference) and sweating (shaking the coins in a bag and collecting the dust worn off).
The Swedish Empire had the greatest and most numerous copper mines in Europe as it entered into its pre-eminence in the early 17th century as an emerging Great Power.
 Through poor fiscal policies and in part the Treaty of Älvsborg, Sweden lost control of its reserves of precious metals, primarily silver, of which most had fled to the burgeoning trade economy of Amsterdam.
 In 1607 the Swedish King Charles IX attempted to persuade the populace to exchange their silver-based currency for a copper-based coin of equal face value, though this offer was not generally taken up.
 Sweden's large army of the time were paid entirely in copper currency, further issued in large numbers by Gustavus II to finance his war against Ferdinand II of Germany.
 The face value of the copper coins in circulation now greatly exceeded the reserves of the state and production of the national economy, and quickly the value of the currency fell to its commodity value, which in a country where copper was so abundant, was small indeed.
 The savings of the people of Sweden were wiped out.
