25 Dollars Giuseppe Garibaldi

Liberia has issued gold coins under its own authority since the 1960s, but the proliferation of small-denomination commemorative gold pieces in the 2000s — many featuring European historical figures with no meaningful connection to Liberia — was driven almost entirely by the international collector market, not domestic monetary policy. These pieces were legal tender in name only, never intended for circulation, and produced by private minting houses under licensing arrangements with the Liberian government.

At 0.73 grams, the gold content is minimal — roughly a third of a sovereign's weight — which places this squarely in the micro-gold category that surged in popularity among European collectors during the mid-2000s commodity boom.
