This $20 coin is one ounce of 99.99% pure silver with a diameter of 38 millimeters and featuring a stunning proof finish, exceptional engraving, and selective color. The reverse design by Canadian artist Glen Loates portrays a scimitar sabre-tooth cat in standing atop a rocky outcrop in a vast grassland. The image, reviewed for scientific accuracy by palaeontologists of the Royal Tyrrell Museum of Palaeontology, presents a full body portrait of the Ice Age predator, with its fierce teeth on display as it opens its mouth. A frosted ice like dome overlays the portrait. The portion of the portrait under the ice is colored, while the remainder of the image is struck only, giving the impression of a colorful window to our land’s ancient past. The reverse includes the text “CANADA” and the date “2018” The obverse features the effigy of Her Majesty Queen Elizabeth II by Susanna Blunt, as well as the coin value of “20 DOLLARS”
