Rare unrecorded commemorative Coin

image shows a commemorative coin celebrating 20 years of nuclear research in South Africa, from 1959 to 1979. The coin features the stylized depiction of a nuclear reactor, likely SAFARI-1, which was commissioned in 1965. The text on the coin reads "20 Years of Nuclear Research" in English and Afrikaans ("20 Jaar van Kernnavorsing").

South Africa's involvement in nuclear research dates back to the post-World War II era, with the establishment of the Atomic Energy Board in 1948. In 1957, South Africa became a member of the International Atomic Energy Agency (IAEA). The country possessed significant uranium reserves, a byproduct of its extensive gold mining industry, and was considered a strategic partner by the United States and the United Kingdom during the Cold War. In the early 1950s, South Africa entered into an agreement to supply its entire uranium output to these two countries.
