10 Dollars - Charles III Blue Whale

At 0.311 g, this belongs to the mini-gold format that the Perth Mint and various Pacific sovereign issuers have leaned on heavily since the mid-2010s — legal tender face values vastly exceeding metal content, issued in limited quantities against Solomon Islands' currency authority. The Blue Whale series follows a well-worn commercial playbook: CITES-listed species, fractional gold, collector-market pricing. Charles III's appearance here reflects the Solomon Islands' continued status as a Commonwealth realm following Elizabeth II's death in September 2022.
