5 Dollars - Elizabeth II Dolphins and Tuna Cyzicus

Cook Islands has issued bullion and collectible gold in extraordinary volume since the 1990s, often under licensing arrangements that keep design and distribution well outside the islands themselves. This particular piece belongs to a series drawing on ancient coinage imagery — Cyzicus, a Greek city on the Propontis, was among the ancient world's most prolific issuers of electrum coinage, with its characteristic tuna a city badge dating back to the sixth century BC.

The KM#3271 assignment places it firmly within the modern Cook Islands collectible program rather than any circulating monetary framework.
