10 Dollars - Elizabeth II To Dear Old Blighty

Part of a series marketed to the British diaspora and expatriate nostalgia market, this miniature gold piece was issued by the Solomon Islands — a Commonwealth realm — lending it nominal legal-tender status while its actual purpose is unambiguously collectible. The Solomon Islands has issued hundreds of such themed coins since the 2000s, functioning essentially as a revenue mechanism through a contracted mint rather than any domestic monetary need.
