25 Dollars - Charles III Santorini

Cook Islands has operated as one of the more prolific licensing authorities for commemorative bullion since the 1970s, routinely issuing pieces with face values that bear no relationship to any circulating currency — the 25-dollar denomination here is a legal tender fiction, the island's GDP-per-capita making 155 grams of fine silver an absurdity as pocket change. The Santorini theme places this squarely in a running series of high-relief colored issues targeting the European collector market, produced under contract by external minting houses rather than any Cook Islands facility.
