In 1997 to celebrate the Buffalo, the South African Mint released a very Limited Issue Natura Buffalo Gold Proof Coin struck in solid fine 999.9% Gold weighing one half of an ounce of pure Gold which is part of the Natura Big 5 series.
The obverse design of the Buffalo Gold Proof Coin depicts a full frontal view of a Buffalo while the reverse design depicts a Buffalo defending itself against an attacking lion.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
