Counterfeit South African coins are made of cheaper metals that have different densities than gold and therefore also different weight. Weight your coin and compare the result with corresponding weight for this coin in a numismatic catalog.

If your coin weights more than 1% more or less than it should (taking into account a level of wear) you may be dealing with a counterfeit.
