I recently was "seized by the moment" and bought a 2009 Canadian $5 Vancouver Olympic Privy Mark Thunderbird (1 ozt silver) coin. I believe it may be a special commemorative issue within the overall Canadian Silver Maple Leaf series. I got it for what I think/hope may be a good price (?)... Unfortunately, I can't find a listing for it in the only world coin value book I have. Can anybody clue me in on what a value range for this coin might be?
