100 Francs CFA You shall not murder

The "You Shall Not Murder" issue is one of several Biblical Commandments coins produced for Central African markets under the Republic of the Congo's licensing agreements with European minting houses — a sovereign mint arrangement that has little to do with domestic monetary policy and everything to do with the global commemorative coin trade. Congo-Brazzaville has issued dozens of such pieces, the face value nominal against a bullion premium many times over.

At 0.5 g of .9999 fine gold, the actual metal content is fractional by any standard, placing this squarely in the collector novelty category rather than investment bullion.
