10 Dollars - Charles III Summer Palace

Issued under the Solomon Islands' long-running program of small-format gold collectibles, which has used the country's nominal currency framework to market precious-metal pieces almost entirely to overseas collectors rather than domestic circulation. The 0.5g format exists because it sits at the lower threshold of economically viable gold striking, keeping the piece accessible as a packaged gift item in Asian and European markets.

Charles III's Summer Palace — Balmoral — passed to him automatically upon Elizabeth II's death in September 2022, the first time in seventy years the estate had changed royal hands.
