10 Dollars - Elizabeth II Posthumous, First Gold Coin

Struck following the death of Elizabeth II in September 2022, this piece was among the first gold issues to appear under the posthumous portrait authorized for Commonwealth realms and territories. The Solomon Islands, though not a realm but a Commonwealth republic, has long issued collector coinage through external minting arrangements — this piece almost certainly produced by a European private mint rather than any domestic facility.

At 0.31 grams, it sits at the lower boundary of what modern minting technology can produce with consistent die registration at .9999 fineness.
