20 Dollars - Charles III Tiger

Cook Islands has issued commemorative silver under its own authority since the 1970s, using New Zealand's currency relationship as a legal basis while contracting striking to private mints — most pieces in this program never circulate on the islands themselves and are produced entirely for the collector market. The 93.3g weight places this squarely in the two-troy-ounce category, a format that became heavily favored by bullion-adjacent commemorative producers after spot silver climbed through the 2010s.

KM#3515 is a recent addition with no documented circulation history to speak of.
