100 Francs Eiffel Tower

Niger has no historical connection to the Eiffel Tower — this is a bullion souvenir issue produced squarely for the collector market, authorized under licensing arrangements that allow small francophone nations to mint legal-tender coins bearing foreign iconography. The 0.5g format places it in a category sometimes called "mini-gold," a segment that expanded aggressively through the 2010s as mints sought entry-level price points for gold buyers.

KM#77 confirms this was catalogued formally, though Niger's own central banking infrastructure plays no meaningful role in its distribution.
