1 Dollar In the name of Elizabeth II, 6th portrait - Creatures of the Deep

The "Creatures of the Deep" series arrives in the final years of Elizabeth II's numismatic presence on Australian coinage — she died in September 2022, meaning these 2023 issues are among the last to carry her effigy before the transition to Charles III. The Royal Australian Mint had already been working through the portrait changeover when this series released, making the sixth portrait's appearance here something of a closing chapter for a reign that spanned every Australian decimal coin since 1966.

Four KM references for a single year and denomination indicate this is a multi-coin set, likely with individually coloured or themed reverses within the series rather than a single type.
