The Belize dollar is the official currency in Belize (currency code "BZD").
 It is normally abbreviated with the dollar sign "$", or alternatively "BZ$" to distinguish it from other dollar-denominated currencies.
Currency depreciation is the loss of value of a country's currency with respect to one or more foreign reference currencies, typically in a floating exchange rate system in which no official currency value is maintained.
 Currency appreciation in the same context is an increase in the value of the currency.
The renminbi (RMB, also known as Chinese yuan; ISO code: CNY) is the official currency of the People's Republic of China.
 Although it is not a freely convertible currency, and has an official exchange rate, the CNY plays an important role in the world economy and international trade.
 This page lists past and present CNY exchange rates with other major currencies, in both nominal and purchasing power parity (PPP) terms.
The Deutsche Mark (] , "German mark"), abbreviated "DM" or    , was the official currency of West Germany from 1948 until 1990 and later the unified Germany from 1990 until 2002.
 It was first issued under Allied occupation in 1948 to replace the Reichsmark, and served as the Federal Republic of Germany's official currency from its founding the following year until the adoption of the euro.
 In English, but not in German, it is commonly called the "Deutschmark" ( ).
This is the list of currencies presently in circulation in Asia.
 The Kuwaiti dinar, the official currency of Kuwait, is the world's most valued currency.

The Fiume krone (Italian: "corona Fiumana" , abbreviated Cor.
 or FIUK) was introduced in the Free State of Fiume on 18 April 1919 by the stamping the previous Austro-Hungarian krone notes by the Italian National Council of Fiume who effectively exercised power in the City.
 After the Dannunzian occupation in September 1919, a new series of notes were stamped on behalf of the "Istituto di credito del Consiglio Nazionale" with a decree dated 6 October 1919.
 The Fiume krone was the official currency of the City of Fiume up to 26 September 1920 when, by the decree of the general Amantea commander of the Italian troops in Fiume, the Italian lira was introduced as the new official currency.
The yen (Japanese: 円 , Hepburn: en , symbol: ¥; code: JPY; also abbreviated as JP¥) is the official currency of Japan.
 It is the third most traded currency in the foreign exchange market after the United States dollar and the euro.
 It is also widely used as a reserve currency after the U.S. dollar, the euro, and the pound sterling.
Endaka (Japanese: 円高 , lit.
 "yen expensive") or "Endaka Fukyo" (Japanese: 円高不況 , lit.
 "yen expensive recession") is a state in which the value of the Japanese yen is high compared to other currencies.
 Since the economy of Japan is highly dependent on exports, this can cause Japan to fall into an economic recession.
In economics, hyperinflation occurs when a country experiences very high and usually accelerating rates of inflation, rapidly eroding the real value of the local currency, and causing the population to minimize their holdings of local money.
 The population normally switches to holding relatively stable foreign currencies.
 Under such conditions, the general price level within an economy increases rapidly as the official currency quickly loses real value.
 The value of economic items remains relatively stable in terms of foreign currencies.
The pound sterling (symbol: £; ISO code: GBP), commonly known as the pound, is the official currency of the United Kingdom, Jersey, Guernsey, the Isle of Man, South Georgia and the South Sandwich Islands, the British Antarctic Territory, and Tristan da Cunha.
 It is subdivided into 100 "pence" (singular: "penny", abbreviated: "p").
 A number of nations that do not use sterling also have currencies called the "pound".
 At various times, the pound sterling was commodity money or bank notes backed by silver or gold, but it is currently fiat money, backed only by the economy in the areas where it is accepted.
 The pound sterling is the world's oldest currency still in use and which has been in continuous use since its inception.
