1 Dollar - Elizabeth II Archaeopteryx

Cook Islands has issued collector dollars under licensing arrangements since the 1970s, with the resulting pieces having no meaningful circulation history and only nominal legal tender status. This Archaeopteryx issue belongs to a sprawling series of natural history-themed coins produced for the wholesale numismatic gift market — the gold plating over copper format is a deliberate cost reduction that keeps retail price accessible while maintaining the appearance of a precious-metal piece.

The specimen itself was first described by Hermann von Meyer in 1861, just two years after Darwin published On the Origin of Species, making its timing scientifically electric.
