This fifth issue in the annual World's Wildlife Series is dedicated to the Ocean Rays (Batoidea), and contains four gold proof coins with different designs and in sizes ranging from one ounce to one tenth of an ounce. The smaller coins were only issued in this set, and not individually. There are two more sizes in the gold series - a five-ounce coin and a half-gram coin, as well as a silver ounce, which are not included.
Rays are one of the most majestic sea creatures on earth, with more than 500 different kinds. The flat, disc-shaped fish can not only be found in the sea, but also in rivers and lakes. Rays have unique anatomical features, such as the special type of gill slits that allow them to filter oxygen directly from the water. Among the most famous species are the venomous stingray, the manta ray and the electric ray.
The set comes in a wooden box and a Certificate of Authenticity. |
