1989 Proposed R2 that was never minted!
The proposed new Two Rand was designed with the Leopard reverse, but this was the animal used by the “Homeland” Bophutatswana and was rejected by the authorities for this reason, hence the current design was chosen. Two types exist for this pattern. The mint admits to 8 being in their vaults. So the number minted is very small! I have personally only seen 4 of which I own 2.
