Cambodia ( Kambuchea) 1974, 50,000 Riels, KM#64, .11941 oz, .900 Fine Gold, neat design showing Cambodian Dancers on Obverse.
Government of Cambodia was toppled just a year later, and the year the US had exited Vietnam. Judging by the scarcity of appearances these coins make we think the already low mintage of 3250 seems a bit high.
