The coins were unveiled Wednesday in Vancouver and Moncton, two of the tournament's host cities, with members of the Canadian team on hand.
The tournament will be held June 6 to July 5 with games also being played in Ottawa, Edmonton, Montreal and Winnipeg.
The Mint will be offering a $20 silver coin sold at face value and designed by artist Joel Kimmel.
