10 Dollars - Charles III Charlemagne

At 0.31 g of gold struck onto a 45 mm planchet, this is unmistakably a foil-type issue — a format pioneered by the Austrian Mint and now widely licensed across Pacific sovereign mints that offer legal tender status without meaningful circulation intent. The Solomon Islands, with no historical connection to the Carolingian Empire, functions here purely as the issuing authority of convenience.

Charlemagne's coronation by Pope Leo III on Christmas Day 800 AD remains one of the most consequential acts of medieval statecraft — a deliberate provocation toward Constantinople and the foundation of a competing imperial claim in the West that shaped European political geography for centuries.
