Australia has two mints, the Royal Australian Mint (which also makes the country's circulating coinage) and the Perth Mint, which are both very active in the bullion coinage space; coins issued by them are legal tender. There are also private issuers of bullion which is not legal tender and is targeted at investors and not at coin collectors - such as this one.
The Pink Panther 2018 10oz Pink Gold Diamond Ingot was produced by the Perth Mint in 2018.
The Mint says about it:
The one and only Pink Panther has been immortalised on this precious metal ingot superbly created from pink gold. Featuring rare pink diamonds handset on both the reverse and obverse, the ingot has been crafted as an exclusive collectable for fans of the hugely popular Pink Panther movies and cartoons.
The reverse of the ingot features a stunning 0.10 - 0.11 carat 4PP Argyle Pink diamond, individually laser engraved with a number and accompanied by its corresponding Argyle Pink Diamonds certificate. The obverse features a smaller 0.05 carat, 4PP, Argyle Pink Diamond. |
