50 Won Kim Il Sung's Birthday

North Korea has issued commemorative currency tied to significant political anniversaries throughout its history, but the 2012 series marks something distinct: it was released for the centenary of Kim Il Sung's birth on April 15, 1912 — an event the state designated "the Day of the Sun" and treated as the most significant occasion in the country's ideological calendar that year. The regime issued multiple denominations under the CS series simultaneously, a coordinated commemorative release rather than a monetary response to any economic need.

Watermark-only security reflects limited production priorities for a note never intended for ordinary circulation. Collector acquisition typically runs through Chinese border trade channels.
