1000 Won UN Forces in Korea

Issued to mark the twentieth anniversary of the outbreak of the Korean War, this piece commemorates the UN intervention that began in June 1950 — the first time the United Nations directly authorized collective military force against an aggressor state. South Korea was the only country on earth with a direct stake in that precedent, and the Bank of Korea's decision to produce a heavy .999 fine silver piece reflects the weight the ROK government placed on that distinction.

KM#13 is a low-mintage commemorative with limited distribution outside South Korea, making it genuinely scarce in Western collections.
