To celebrate Queen Elizabeth II's 95th birthday, the Royal Canadian Mint issues a $20 coin that shows her in four different portraits – the royal effigies used on Canadian coins. On the reverse you see her monument (https://en.wikipedia.org/wiki/Parliament_Hill#/media/File:Queen_Elizabeth_statue_full_Ottawa.jpg) in Ottawa. From what I have read, this is a 1 oz silver piece which can also be had in a British-Canadian coin set.
