25 Dollars - Elizabeth II Pultusk Meteorite

The Pułtusk meteorite fell over northeastern Poland on January 30, 1868, producing one of the largest recorded meteorite showers in European history — estimates range from several thousand to over 100,000 individual stones scattered across a wide strewnfield. Cook Islands authorized a series of meteorite-inclusion bullion coins in the mid-2000s, embedding certified fragments directly into the reverse field. The Pułtusk material is an H5 ordinary chondrite, and the specific fragment set into each coin was sourced from authenticated museum-grade stock.
