5000 Pesetas Guineanas Francisco Macias

Equatorial Guinea gained independence from Spain in October 1968, and Francisco Macías Nguema almost immediately began consolidating power through a campaign of extraordinary brutality — by 1972 he had declared himself president for life, and by 1979 his nephew Teodoro Obiang Nguema toppled him in a coup and had him executed. This coin was struck just two years into that regime, when international mints were still willing to produce prestige gold issues for the new nation.

The piece was almost certainly struck by the Spanish Mint on contract, part of a broader proof series intended for collectors rather than circulation. At 70 grams of .900 gold in a 65mm format, it is among the largest and heaviest coins ever issued under the Macías government — a government that would soon become too pariah to attract such commissions.
