2017 - $20 - 1 oz. Pure Silver Coin - Nocturnal by Nature: The Little Brown Bat

From the edge of the Arctic tundra to the Great Lakes, the little brown bat (Myotis lucifugus) owns the night by using echolocation to locate its insect prey. Our Nocturnal by Nature series continues its exploration of a nocturnal Canada, using selective black rhodium plating to set the tone for a night-time encounter with the diminutive flying mammal.
