A hippopotamus appears on the reverse of this large silver crown. Silver content is .9635 of an ounce. Queen Elizabeth II appears on the obverse. Only 4,500 were issued. One of the scarce coins to depict a hippo. For the longest time this coin was and may still be the only 8 shillings issued in the world. A tough coin to find, especially in pristine condition! KM#7a.
