The one kilogram Benin “Nature in Danger – Great Barrier Reef“ was designed by the recognized P. de Greef artist Beni Debacker. The incredible reverse design highlights the beauty and diversity of the one of seven Natural Wonders of the World, the Great Barrier Reef. In contrast, the obverse shows the threat that pollution poses to life on the reef in very dramatic fashion. The double sided ultra-high relief minting gives the motif a three dimensional character. The lifelike vibrancy is achieved through a unique combination of vivid coloring and glass enamel – a masterpiece of traditional craftsmanship with an exclusive issue of just 99 coins.
