Do You Dare Take This Tiger by the Tail? From its stripes to its ferocious hunting habits, it’s no wonder how this shark got its name. They’re found in the Atlantic Ocean, including Tristan da Cunha, where this proof coin was minted. Each 2015 One Crown Tiger Shark proof is struck in 25 grams of copper and layered in silver. Tiger sharks have been nicknamed the ‘wastebasket of the sea’ because they eat just about anything, including tires and license plates! Each proof comes with an information card about Discovery’s Shark Week. The mintage is limited to 15,000. Shark Week fans are poised to attack. Order now before the last of them are devoured!
