The 5c coin will, however, remain legal tender and the public is encouraged to continue to recirculate this coin together with all South African coins. Accordingly, all banks and businesses are obliged to continue to accept the 5c coins as legal tender.
In an effort to reduce the production cost of coin, the current 10c bronze alloy coin will be replaced with a new 10c denomination coin which will be a copper plated steel coin. There will be no changes made to the themes on the 10c coin.
