These coins were issued in celebration of the Centennial and show a bobcat (lynx) rather than a cougar. They were originally struck in an alloy of 80% silver and 20% copper but halfway through the year rising silver prices forced the Royal Canadian Mint to debase the coins to 50% silver. Roughly 24 million of each type were minted; it's difficult to tell them apart on sight.
