5 Dollars - Elizabeth II St. Andrew

The St. Andrew series from Cook Islands is part of a broader wave of licensed commemorative silver issued through the New Zealand Mint, which has produced collector coinage for Cook Islands since the 1970s under a long-standing arrangement that exploits the territory's nominal sovereignty without requiring any domestic minting infrastructure. Cook Islands has no mint of its own; every coin bearing its authority is struck elsewhere.

The 25-gram specification sits outside both the standard one-troy-ounce and half-ounce formats, a deliberate commercial choice to distinguish the piece from bullion while keeping silver content high enough to justify the precious-metal premium.
