New Zealand - Hamilton's Frog - Official (6) Coin Silver Proof Set - 2008 - Mint Issued Presentation Case - This 2008 six coin set features the rarest frog in New Zealand and possibly the world - Hamilton's frog (Leiopelma hamiltoni). Hamilton's frog is one of the most critically endangered species, with less than 300 adults in the wild today.
It is widely believed to be the most ancient of all frogs and has unique characteristics. This native New Zealand frog does not live in water habitats and prefers a range of forest environments which, over time, has led to the loss of webbing between its toes. Unlike other species, Hamilton's frog has limited vocal capacities.
