The Mann Cup is the trophy awarded to the senior men's box lacrosse champions of Canada. The championship is a best-of-seven, East vs West series played between the league champions of Major Series Lacrosse, the East, and Western Lacrosse Association, the West. The original trophy is now permanently located in the Canadian Lacrosse Hall of Fame. It is one of the most valuable in all of sports; made of solid, albeit low-karat, gold, the trophy was valued at CA$60,000 (equivalent to $193,091 in 2021) when appraised by Birks in May 1980.
