The first issue of the coin series Australia at night is dedicated to the platypus. This coin in proof quality shows a realistic illustration of the platypus under water. The Black Proof finish of the silver coin clearly distinguishes the platypus from the background. The platypus (Ornithorhynchus anatinus) is a mammal that lays eggs and lives only in Australia. The unusual mammal has a duckbill and a tail that looks like a beaver. The male platypus has a spur on the hind foot, which can give off a poison. The platypus is the only living representative of its kind. 

Note: outer box has signs of wear as per images, the coin remains in perfect condition.
