25 Dollars - Elizabeth II Year of the Pig

Cook Islands has issued lunar series coinage in quantity for decades, with the underlying bullion content — not sovereign circulation — driving production. The 2019 Year of the Pig corresponds to the final year of the 12-year Chinese zodiac cycle, a detail manufacturers of these issues exploit for marketing to both bullion buyers and collector audiences simultaneously.

At 155.5 grams of .999 silver, this is a 5-troy-ounce piece — a format that became standard across Pacific island issuing authorities after Perth Mint demonstrated the format's commercial viability in the early 2000s.
