2018 Tickey CAT Scan – Sterling Silver 2 1/2 Cents

Description

Part of the South African Mint’s popular “South African Inventions” series, the 2018 2½ Cents Sterling Silver Tickey honours the ground-breaking invention of Computed Tomography (CT/CAT scanning). The revolutionary medical technology was pioneered by South African-born physicist Allan McLeod Cormack, whose theoretical calculations led to the 1979 Nobel Prize in Physiology or Medicine.

The coin’s reverse depicts a human head showing a stylized brain scan alongside the text “Computed Tomography” and the year “1956”—the year Cormack published his seminal work. The obverse features the traditional king protea, South Africa’s national flower. Weighing 1.414 grams and measuring just 16.3mm in diameter, this small-denomination “tickey” proof coin represents a miniature tribute to one of modern healthcare’s most vital medical breakthroughs.
