25 Dollars - Elizabeth II 6th Portrait - Kangaroo - Gold Bullion Coin

Australia's gold kangaroo bullion series has been issued continuously since 1986, making it one of the longer-running national gold programs. Unlike many bullion series, the kangaroo design changes annually — a deliberate policy adopted in 1989 partly to stimulate collector demand alongside pure investment buying, and one that has arguably complicated secondary-market liquidity for non-current dates ever since.

The sixth portrait of Elizabeth II, by Jody Clark, entered circulation on Commonwealth coinage in 2015 following the phased retirement of Ian Rank-Broadley's fifth effigy.
