10 Dollars The Bank of Namibia

Namibia's gold coinage program has always occupied an awkward niche — struck primarily for the collector and bullion markets rather than any genuine monetary function, with mintages kept deliberately low to sustain secondary market premiums. KM#23 dates to a period when the Bank of Namibia was actively expanding its commemorative and precious-metal issues following two decades of independence from South African administration, granted in 1990 after a prolonged UN-supervised transition.

At just over a gram, the coin's gold content sits below the threshold most institutional buyers track.
