American Platinum Eagle
The American Platinum Eagle is the official platinum bullion coin of the United States. These coins are made of 0.9995 pure platinum with face values of 10, 25, 50 and 100 dollars and were first released by the United States Mint in 1997. The design of coins of different values is almost the same, except for some numerical values.

Platinum Koala
The Platinum Koala is the most famous series of Australian platinum coins. On 18 June 1987, the Australian Government approved the minting of platinum and silver coins, and accepted them as legal tender. This decision was made based on the success of gold coins issued a year earlier. The minting of the "Platinum Koala" began in September 1988 in Perth. For marketing purposes, 2 ounce, 10 ounce, and 1 kilogram coins of silver, gold and platinum were introduced in 1991; the 1 kg coins were the world's heaviest bullion coins at the time.[69]
The obverse, designed by Raphael Maklouf for most issues, depicts Elizabeth II, and the reverse contains an image of a koala. The initials of the reverse face designer James Brown are present on most coins. The annual series contain coins weighing from 1/20 ounce to 1 kilogram.[70]
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
Platinum Panda
The Platinum Panda is a series of platinum coins of China produced from 1987 to 2005. The series is named after the image of giant panda printed on the reverse of all coins. The People's Bank of China minted 8,300 one-ounce Platinum Panda coins between 1987 and 1990 with a face value of 100 yuan. Additionally, 5,450 ounces of platinum were used for coins of smaller denominations in the 1990s through the first decade of the 21st century. Minting was discontinued in 2005.
