Important features and characteristics
First minted in 1987
On January 30, 1987, the first limited coin minted with the mint mark GRC – for the Barnib Group, later part of the First National Bank – took place.
Private mintings from 1988
Starting in 1988, coin subscribers could request their own minting. Each issue was delivered with a numbered certificate signed by representatives of the SA Mint and the GRC. A special feature: the minter also received a photo taken during the minting process.
Variants and misprints
In the course of 1988, changes in the process resulted in four minting variants :
-
Ghost Image by Paul Kruger (Double Image)
-
Proof coins with incorrect dates (88)
-
Half ounce with Ghost Image
-
Krugerrand with small underline under “Fyngoud”
These misprints are extremely rare and highly sought after.
Anniversary edition 2007
To mark the 40th anniversary of the Krugerrand minting, the GRC issued a 1 kg Krugerrand gold coin (99.99% fine gold, mintage: only 40 pieces) – with its own GRC mint mark.
