2015 Australian Koala Silver Proof High Relief Coin 1oz
The coin’s reverse depicts an adult koala sitting in the fork of a eucalyptus tree, amid a rural landscape. The design includes the inscription AUSTRALIAN KOALA, The Perth Mint’s ‘P’ mintmark, and the 2015 year-date.
The coin’s high relief reverse and obverse are minted on concave surfaces to ensure the optimum flow of metal is achieved by the strike of the die. Each coin is struck from 1oz of 99.9% pure silver in proof quality.
