25 Dollars - Charles III Pearl Harbor

Cook Islands has issued commemorative silver under its own authority since 1972, a function of its self-governing status in free association with New Zealand. The Pearl Harbor attack of December 7, 1941 killed 2,403 Americans and brought the United States into a war it had spent two years officially avoiding. At 155.5 grams of .9999 fine silver, this is a five-troy-ounce piece — a format increasingly favored by Pacific island issuers whose commemorative programs are funded almost entirely by collector sales rather than circulation revenue.
