1 Dollar - Elizabeth II Campo del Cielo

Campo del Cielo — "Field of Heaven" in Spanish — refers to a strewn field in the Gran Chaco region of Argentina where an iron meteorite shower fell roughly 4,000 to 5,000 years ago. The craters were first officially recorded by Spanish conquistadors in 1576, who had learned of the site from indigenous accounts describing iron fallen from the sky. The meteorite's total recovered mass now exceeds 100 tonnes across dozens of individual fragments.

Niue has issued a series of coins incorporating genuine meteorite material, each piece containing a fragment of the specific meteorite named on its face. The iron composition here is not an alloy choice — it is the meteorite itself.
