The size of this gold coin is a favourite among collectors not only because of its affordability, but also because of the intricate artwork it bears. The Creatures of Myth & Legend 0.5g Gold Unicorn Tokelau Proof Coin is highly sought after because of its size and its artwork.
The reverse side of this coin features an elusive unicorn emerging from a forest. He is standing with one hoof raised, as if in pensive contemplation, and he is partially shrouded in foliage. The mirrored field behind the relief on this gold coin augments the beauty of this mythological creature. Known for being fierce and wild, the unicorn symbolises grace and purity, and this Tokelau gold coin carries the unicorn’s grace in its design and the unicorn’s purity in its gold.
The unicorn has taken on many symbolic interpretations in diverse cultures throughout history. The unicorn has been associated with chastity, the Word of God, longevity, and harmony. |
