Vietnamese dong
The dong (Vietnamese: đồng; ; Vietnamese: [ˀɗɜwŋ͡m˨˩]; sign: ₫ or informally đ and sometimes Đ in Vietnamese; code: VND) is the currency of Vietnam, in use since 3 May 1978. It is issued by the State Bank of Vietnam. The dong was also the currency of the predecessor states of North Vietnam and South Vietnam, having replaced the previously used French Indochinese piastre. Formerly, it was subdivided into 10 hao (hào), which were further subdivided into 10 xu, neither of which are now used due to inflation. The Vietnamese dong has increasingly moved towards exclusively using banknotes, with lower denominations printed on paper and denominations over 10,000 dong, worth about 40¢ dollar or euro, printed on polymer. As of 2022, no coins are used. Generally, Vietnam is moving towards digital payments. The 500,000-dong note (VND) is the highest-denomination banknote in circulation in Vietnam. The note is dark blue in color and has been in circulation since 2003. As of September 2025, the Vietnamese dong is the third-lowest valued currency unit (behind the Iranian rial and the Lebanese pound), with one United States dollar equaling 26,387 dong.
Russian Ruble
The ruble or rouble (Russian: рубль, romanized: rublʹ; symbol: ₽; ISO code: RUB) is the official currency of the Russian Federation. Banknotes and coins are issued by the Central Bank of Russia, which is Russia's monetary authority independent of all other government bodies. The ruble is the second-oldest currency in continuous use and the first decimal currency. The ruble was the currency of the Russian Empire, which was replaced by the Soviet ruble (code: SUR, 810) during the Soviet Union. Following the dissolution of the Soviet Union, by 1992, the Soviet ruble was replaced in the Russian Federation by the Russian ruble (code: RUR, 810) at par. The Russian ruble then further continued to be used in 11 post-Soviet states, forming a "ruble zone" until 1993. The ruble was further redenominated with the new ISO 4217 code "RUB, 643" just preceding the 1998 financial crisis, and was exchanged at the rate of 1000 RUR = 1 RUB. Code "RUR, 810" was then excluded from both the ISO 4217 standard and the Russian currency classifier, but continues to be used for numbering bank accounts internally within Russia. The ruble is a free-floating currency and is subdivided into 100 kopecks which have fallen out of use due to inflation. In 2023, the digital ruble was introduced. The Russian ruble is also used as a de facto legal tender in Baikonur, Abkhazia and South Ossetia.
