2 Dollars - Elizabeth II Impact Moments Meteorite

The Muonionalusta meteorite was discovered in northern Sweden in 1906, though it impacted Earth roughly one million years ago and is classified as a fine octahedrite — one of the oldest known meteorite types, with an estimated crystallization age exceeding 4.5 billion years. Slices cut for collector inserts reveal the Widmanstätten pattern, a crystalline structure that forms only over millions of years of slow cooling in space and cannot be replicated artificially.

Niue's licensing arrangement with the New Zealand Mint has made it a vehicle for this kind of novelty bullion since the 1990s. The sovereign status is real; the connection to the subject matter is purely commercial.
