Ghana's Bank has produced a series of novelty bullion pieces under the 5 Cedis denomination that bear no meaningful relationship to domestic monetary policy — they are unambiguously produced for the international collector market, with the Ghanaian legal tender designation functioning as the legal mechanism that allows a sovereign mint to authorize private-issue commemoratives.
The "3D illusion" effect is achieved through a lenticular or prismatic die-cutting technique refined by several European minting houses over the past decade, most visibly popularized by the Czech Mint and Coin Invest Trust of Liechtenstein.
