5 Dollars - Elizabeth II Girl with a Pearl Earring

The "Girl with a Pearl Earring" series from Cook Islands falls into a crowded category of art-themed bullion issues that proliferated sharply after 2015 as mints competed for the collector-investor crossover market. Cook Islands has no meaningful connection to the painting, Vermeer, or the Dutch Golden Age — the attribution is purely a licensing and legal convenience, as the island's framework allows foreign mints to issue under its authority with minimal regulatory friction.

At 1.56 g of .9999 gold, this is a fractional piece sized to hit a accessible price point rather than any historical weight standard.
