The species inscription GREY KANGAROO appears in the lower field beneath the animal. The surrounding legend, arranged around the beaded border, reads THE AUSTRALIAN NUGGET at the top and 1 OZ. 9999 GOLD along the right, with the date 1991 at the base. |

| Additional information |
The Grey Kangaroo gold proof was part of Perth Mint's push in the late 1980s and early 1990s to establish Australia as a serious competitor in the international bullion and numismatic gold market, directly challenging the South African Krugerrand and the Canadian Maple Leaf. The .9999 fineness — four nines — was a deliberate marketing and metallurgical choice, exceeding the Maple Leaf's then-standard .9999 purity claim and positioning Australian product as the benchmark for fine gold coinage.
KM#144 spans two calendar years, with dies and packaging differentiated by date. The 1991-dated pieces saw lower collector uptake as the series was already maturing.
