正面描述 The obverse features the national coat of arms of Burkina Faso at center, depicting a shield charged with a star and flanked by two horses rampant, with an open book at the base and a ribbon bearing the national motto 'Unité Progrès Justice.' Above the arms, a banner reads 'BURKINA FASO.' The circular legend 'REPUBLIQUE DU BURKINA FASO' arcs across the upper field, while the denomination '1000 FRANCS CFA' appears in the lower field. At the bottom, a small inset color image of the Earth's moon is applied as a decorative element. The coin's concave field is finished in a handmade premium antique style, with a textured rocky border evocative of a meteorite surface surrounding the central devices. The specification '1 oz Ag 999' is inscribed along the right inner border.

附加信息

NWA 7325 was recovered in 2012 from the Sahara and generated immediate controversy — its unusually low iron-to-magnesium ratio and oxygen isotope signature led a team including Anthony Irving to propose a Mercurian origin, which would make it the first recognized sample of material from the innermost planet. The claim remains contested; some researchers favor a distinct achondrite parent body that has not yet been identified.

NWA 8409 is a paired stone from the same fall. The embedded meteorite fragment gives this coin its only real claim on a collector's attention.
