Klondike Mike 999 silver token

I have a pair of Klondike Mike salutes Edmontons Pioneers, Commonwealth Games 1978, 999 silver tokens. Trying to obtain some information on them, like silver weight and value. This site has mintage information (500), but that's all. Can anyone assist me? Thank you.

 Welcome to the site.

 On that page I see the 500 minted for the silver you mentioned; then below it I also saw 35 only minted for the gold version. And here is one of those ...

 which sold (in 2007 admittedly) for 650 dollars. Not sure if that helps, but that was the price for the rarer issue in rarer metal. Maybe with rising prices that might be what the silver version is worth nowadays - I can't find anything else.  

Welcome !
