The modern real was introduced in 1994 as part of the Plano Real, a substantial monetary reform package that aimed to put an end to three decades of rampant inflation. At the time it was meant to have approximately fixed 1:1 exchange rate with the United States dollar. It suffered a sudden devaluation  to a rate of about 2:1 in 1999, reached almost 4:1 in 2002, then partly recovered and has been approximately 2:1 since 2006. The exchange rate as of January 22, 2010 is approximately BRL 1.82 to USD 1.00. [Wikipedia]

The currency was originally known as the tical; this name was used in the English language text on banknotes until 1925. However, the name baht was established as the Thai name by the 19th century. Both tical and baht were originally units of weight and coins were issued in both silver and gold denominated by their weight in baht and its fractions and multiples.

On June 23, 2009, the Bank of Korea released the 50,000 Won note. On the front a portrait of Shin Saimdang, a prominent 16th-century female artist, calligrapher, and mother of Confucian scholar Yulgok can be seen. Yulgok is also known as Yi I, whom we can find on the 5,000 Won note. This note is the first Korean banknote that features the portrait of a woman. 100,000 won notes were also announced, but their release was later canceled. However, there has been many complaints about how the new 50,000 won note looks very similar to the 5,000 won note. [Wikipedia]

The wŏn became the currency of North Korea on December 6, 1947, replacing the Korean yen that was still in circulation. It was revalued at a rate of one hundred to one in 1959. North Korean wŏn are intended exclusively for North Korean citizens, and the Bank of Trade issued a separate currency (or foreign exchange certificates) for visitors, like many other socialist states. However, North Korea made 2 varieties of foreign exchange certificates, one for visitors from "socialist countries" which were colored red, and the other for visitors from "capitalist countries" which were colored blue/green. In recent times, FECs have been largely depreciated in favor of visitors paying directly with hard currency, especially the euro. [Wikipedia]
