This 99.99% pure gold coin is the third in the Royal Canadian MintÕs best-selling series of 11-millimetre gold coins. The powerful Rocky Mountain Bighorn Sheep is one of CanadaÕs most distinctive and identifiable wild sheep species. The reverse design by Emily Damstra, rendered in exceptional detail despite the coinÕs miniscule size, features a profile view of the statuesque curly-horned head of an adult Rocky Mountain Bighorn ram. Exquisite detailing highlights the annulus ridges of the regal ruminantÕs blunt-ended left horn, which curls to within centimetres of its far-seeing eyes. The animalÕs dark, short hair and light-coloured muzzle are brought to life through fine detail and engraving.
