This third and final coin in the award winning Perth Mintís 'Shark Series' features an engraving of the fierce and solitary tiger shark. The fourth-largest shark in the world, they get their name from the youthful stripes on their skin that fade as they get older. The popular Australian series began in 2014 and each issue has had a mintage of 300,000 or less. These Tiger Shark coins are denominated 50 cents and contain half an ounce of .9999 fine silver. Queen Elizabeth II graces the obverse of the Brilliant Uncirculated 2016 issue.
