5000 Francs CFA A Starry Night in Paris

Chad's monetary authority has issued a long-running series of large-format collector pieces under the CFA franc designation, though Chad itself uses the Central African CFA franc governed by the BEAC — an arrangement inherited from French colonial monetary architecture that, notably, still ties member states to French Treasury convertibility guarantees. These coins are struck entirely for the numismatic export market; none enter circulation in N'Djamena or anywhere else.

The silver-plated copper construction — roughly one ounce of fine silver over fourteen of copper — keeps production costs low while allowing legal tender face values that bear no relationship to intrinsic metal worth.
