I usually deal with US Coins and Proof Sets, so i don't know much about this. Any help would be of use. I found this 1992 Canadian 125th Anniversary Commemorative Proof Set on a website for sale that I have used before. The set is $89.99 plus shipping. This is the description the site gives: This commemorative proof set was beautifully put together to celebrate the 125th annivesary of Canada in 1992. The set contains 12 sterling silver quarters and one commemorative loon coin. Each of the 12 quarters features a unique design honouring one of the 10 canadian provinces and the (then) two territories. Each gem proof coin in this set is encapsulated and comes in an attractive blue velvet lined case which is protected by a white cardboard sleeve with the Canada 125 logo on it. Also included is a set of 12 certificates of authenticity (COA) for the quarters and also one more for the loon dollar.
