Sleepy and placid koala

The unique charm of Australia’s sleepy and placid koala is beautifully illuminated on this prestigious gold coin that is crafted with assiduous attention to detail to meet the expectations of our most fastidious collectors.

Appealing reverse design

The coin’s reverse features an artistic impression of a koala in its customary habitat – the canopy of a eucalyptus tree.  Recognised throughout the world as one of Australia’s remarkable native animals, the docile creature is surrounded by representations of gum leaves and two delicate blossoms.
