100 Francs California Gold Rush

The Republic of the Congo has no historical connection to the California Gold Rush of 1848–1855, and these small-format gold issues are frankly collector constructs — low-weight bullion pieces issued under licensing arrangements that allow sovereign minting authority to attach foreign historical themes to legal tender coinage. The California rush itself began when James Marshall spotted flakes at Sutter's Mill in January 1848, a discovery John Sutter desperately tried to suppress to protect his land grants. He failed within weeks.
