3000 Francs CFA Subpolar Zone

Chad has issued gold coins under the Central African CFA franc system despite having no domestic mint — these are produced by the Bavarian State Mint in Munich under licensing arrangements that have generated considerable controversy among numismatists over the legal standing of such issues. At 0.057 g, this is among the smallest gold coins struck by any recognized issuing authority, a category that attracts aggressive collector speculation but limited secondary market liquidity.
