3 Dollars - Elizabeth II Koala

The Koala bullion series is an Australian product — Perth Mint issues — but Cook Islands licensing arrangements have long allowed foreign mints and private dealers to attach Cook Islands denominations to small-format gold pieces for legal tender framing purposes. This particular $3 face value is essentially nominal, a compliance artifact rather than a monetary reality. Perth Mint's .9999 fine koala-themed gold has been struck in fractional weights since the 1980s, making the series one of the longer-running fine gold programs in the Asia-Pacific region.
