2 1/2 Cents 1st decimal series

South Africa's decimal conversion on 14 February 1961 — "Decimal Day" — replaced the pound system with the rand, and this tiny denomination was part of that inaugural series. The 2½ cent was almost immediately recognized as impractical, an awkward fraction surviving only because price structures during the transition still demanded it. The series ran just four years before the denomination was quietly discontinued.

The .500 fine silver content reflects a deliberate cost-reduction from pre-decimal standards, not a wartime compromise.
