10 Dollars - Charles III Elizabeth Tudor

The geometry here is immediately suspicious: at 45 mm diameter and 0.31 g of gold, this is a foil-thin planchet — a format favored by certain Pacific island mints for high-denomination collector issues that maximize visual surface area while minimizing metal cost. Solomon Islands has issued sovereign legal tender under Royal Australian Mint and various private mint arrangements for decades, with the nominal face value bearing no relationship to either metal content or purchasing power in Honiara.

The "Elizabeth Tudor" designation references the late Queen's formal dynastic surname — rarely used on coinage — paired with the regnal name of Charles III, who acceded in September 2022.
