King Gojong of Joseon made great efforts to establish a modern monetary system in his kingdom, launching a plan to issue a new set of coins made at the Central Government Mint (Jeonhwanguk), which was founded in 1883 according to the proposal of his German advisor, P. G. von Möllendorff. The government of Joseon imported blanks and coin dies from Germany and minted two of Korea’s first modern coins, a 1-nyang silver coin and a 5-mun tin test coin, in 1885. The coins are called Euryu Test Coins because they were minted in the Euryu Year (i.e. 1885). Of the two, the 1-nyang test coin bears on its front face a Taegeuk symbol with a plum spray, symbolizing the Joseon royal family, and on its rear face a dragon, symbolizing the royal authority, with inscriptions of the minting date and denomination along its edge.
