The second coin of 5 from the treasure of Smaug the Terrible is a decagonal shape and features a ship under sail on one side and an image of the Arkenstone on the back. It measures about 1 1/2-inches across. The Hobbit The Desolation of Smaug Coin 2 is an exact replica, drawn from a mold of the original coin created for The Hobbit: The Desolation of Smaug by the 3 Foot 7 Art Department. Made from zinc alloy metal plated to look every bit as precious as if it were made of solid gold, the coin comes packaged with a backing card in a zip-loc bag. Ages 14 and up.
