Two Cent Earrings – 1967 Edition. Crafted from bronze 2 cent coins minted in 1967, the very first year of decimal currency in New Zealand. That year, approximately 140 million 2 cent coins were struck — marking a major moment in the nation’s monetary history. These feature the beloved kowhai flower, delicately curled into a concave pendant to catch the light and honour the coin’s original form.
