Here's one of my favorite designs on a Canadian coin - the 2009 commemorative $5.00 coin that marks the 80th anniversary of the opening of a Canadian embassy in Japan.
I'm a big fan of allegory on coins. This coin's commemorative design is fully allegorical, using local flora and fauna to represent each country -- a white-tailed deer and maple tree for Canada (at right), and a shika deer and cherry blossom tree for Japan. The two deer stand side-by-side, to symbolize the friendly, harmonious relations between the two countries. To the left of the shika deer is seen the Japanese character "Wa" which translates into English as "harmony."
