2018 CAT Scan Crown – Sterling Silver R2

Description

Part of the South African Mint’s acclaimed “South African Inventions” series, the 2018 R2 Sterling Silver Crown honours the ground-breaking development of Computed Tomography (CT/CAT scanning). The revolutionary technology was pioneered by South African-born physicist Allan McLeod Cormack, whose theoretical calculations in 1956 earned him the 1979 Nobel Prize in Physiology or Medicine.

The coin’s reverse depicts a stylized cross-section of a human head, representing the target area of a diagnostic scan alongside the year “1956” and “Computed Tomography”. The obverse displays South Africa’s national coat of arms flanked by the nation’s name in its official languages. Struck in 1 troy ounce of fine silver (within a 33.626g sterling silver alloy) with a brilliant proof finish, this issue celebrates one of the most vital medical breakthroughs in modern history.
