1000 Won

The 1975 series marked a significant moment in South Korean printing history — prior issues of the 1,000 Won had been contracted to foreign security printers, and this note was among the early high-denomination pieces produced entirely domestically by the Korea Minting and Security Printing Corporation in Daejeon. That shift was a deliberate policy decision by the Korean government to reduce dependence on overseas printers, particularly in the wake of rapid industrialization during the Third Five-Year Economic Plan.

Watermark-only security at this denomination now looks thin, but it reflected the available domestic production capability at the time.
