1 Dollar - Elizabeth II 4th Portrait - Australian Saltwater Crocodile

Part of the Perth Mint's long-running lunar and wildlife bullion programs, this release belongs to a series that has made the mint one of the dominant players in the global silver bullion market since the 1990s — a position built largely on collector demand from East Asia, particularly China. The saltwater crocodile issue capitalized on sustained international appetite for Australian fauna themes, with mintage figures capped to maintain secondary-market premiums.

Elizabeth II's fourth portrait, by Ian Rank-Broadley, was introduced in 1998 and remained in use until 2015.
