Australia's gold koala bullion series has been issued by the Perth Mint since 1986, distinguished from most major bullion programs by an annually changing reverse design — a deliberate policy intended to encourage year-on-year collecting rather than straightforward bullion accumulation. The 2017 issue falls within the Ian Rank-Broadley obverse portrait period, the fourth effigy of Elizabeth II adopted by Australian coinage in 1999.
The two-troy-ounce format places this piece in a tier produced in comparatively small numbers relative to the one-ounce flagship, making survival in original Perth Mint packaging the norm rather than the exception for the series.
