1 Dollar - Elizabeth II 6th Portrait - Silver Kangaroo

The "sixth portrait" designation refers to the Jody Clark effigy of Elizabeth II, introduced across Commonwealth mints from 2015 onward — Australia adopted it with some reluctance, given the Royal Australian Mint's historical preference for the Ian Rank-Broadley version it had used since 1998. The Silver Kangaroo bullion program itself launched in 2015 as a direct competitive response to the Perth Mint's Kangaroo series, an unusual instance of two Australian government mints running parallel silver bullion programs aimed at the same international buyer market.

The .999 fineness puts it fractionally below the Perth Mint's .9999 standard — a distinction some bullion buyers treat as meaningful.
