5 Dollars - Charles III Flamingo

Cook Islands has issued wildlife-themed bullion and collector silver under its own authority since the 1970s, a practice that has little to do with any domestic economy — the islands use the New Zealand dollar in daily commerce — and everything to do with the numismatic export market. The $5 denomination is a recurring face value in this program, set low enough to satisfy legal tender technicalities without any pretense of real circulatory intent.

The flamingo subject places this squarely in a long-running series of exotic fauna issues from this issuer, dated 2026 but almost certainly struck before that year reaches the calendar.
