 Korea

The first Korean stamps were issued by the Joseon Dynasty issued on 18 November 1884 when the first postal service was created. While five values were printed - 5, 10, 25, 50, and 100 mon, only the 5m and 10m values were issued, and even these saw little use, as the post office was burned down during a revolt in December 1884.

The start of Korean Empire saw currency change in 1900, to rin, cheun, and weun, necessitated new stamps, and a series of 13 was issued, from 2 rin to 2 weun. In 1910, Japan assumed administrative control of Korean Empire, and subsequently all mail used Japanese Chosēn stamps until early 1945 after liberation. [source: wikipedia]
