Between the rocky mountains of Thessaly and Arcadia, there exists an incarnation of the Greek creature, in which the wild inhabitants of the mountains and the restless spirits of the forests were combined in a half-man, half-horse being. MINT XXI has created a true embodiment of wildness and defiance. The high relief technique details the masculinity of the centaur on the 1 ounce coin. The accuracy of his arrow is conveyed through selective gilding that emphasizes his frenzy, exuberance, and unrestraint.
