2000 Francs CFA Stanislaw Lem's Invincible

Cameroon's CFA franc issues have become a vehicle for the global novelty bullion market, with the BCEAO lending its authority to pieces designed, minted, and marketed almost entirely outside the country. This 200-gram format is a product of that arrangement — Lem's 1964 novel gets the treatment here, a Polish science fiction classic that spent decades suppressed in some Eastern Bloc markets for being insufficiently optimistic about machine intelligence.
