10 Dollars - Elizabeth II Kookaburra

Part of the long-running Australian Kookaburra bullion program adapted for Solomon Islands legal tender issue, this fractional piece exists primarily as a low entry-point collectible for the bullion market rather than as a circulating coin. At 0.5 g of .9999 gold, it contains just under one sixty-fourth of a troy ounce — a format that became commercially viable only after improvements in micro-striking technology during the 2000s made consistent quality at this scale achievable.
