1 oz Gold Kangaroo (In Plastic, Varied Year)

The Australian Gold Kangaroo coin hasn’t always displayed a Kangaroo. When the series first started in 1986, the original design showed an image of a simple gold nugget. This meteorite-looking image wasn’t physically desirable, leading to low public interest.

After three years, the Perth Mint decided to change the coin's design to feature one of the country’s leading animals, the Kangaroo. But because the series was originally a gold nugget, the coin is still occasionally called the Australian Gold Nugget Coin.
