5 Dollars - Elizabeth II 6th Portrait - Saltwater Crocodile - Silver Proof

The saltwater crocodile (*Crocodylus porosus*) is the largest living reptile on earth and the only Australian megafauna predator to have survived the Pleistocene extinctions largely intact — a fact that lends the subject genuine zoological weight rather than tokenistic wildlife symbolism. The Royal Australian Mint's "Australian Animals" bullion and proof series has drawn on this kind of ecological longevity repeatedly, positioning Australia's extant apex fauna against a global collector market increasingly receptive to high-fineness silver issues from Commonwealth mints.

The sixth portrait of Elizabeth II, by Jody Clark, was adopted by the RAM in 2019.
