The Platinum Koala never reached the popularity of the American Platinum Eagle, mostly because it has not been advertised in the US. Like most investment platinum coins, Platinum Koalas are sealed in a protective plastic case. The coins are sold at prices that reflect the current price of platinum, and not at the face value printed on the coin. Since November 1986, the Perth Mint has used more than 18 tonnes of platinum for minting. About 85% of the coins were sold abroad making the Gold Corporation (owner of the Mint) one of Australia's top 30 export earners.
