Signed Olympic Water bottles?

I have 5 Mcdonald's Olympic 2010 watter bottles. 4 out of five of them are signed by the athlete on the bottle. I have a signed Bottle of -- Cindy Klen, Patrick Chan, Brad Martin, And i have the hockey bottle signed as well, but i am unsure of who's it is. a few people say it was Sidney Crosby, but i am unsure. We actually won them in a contest, and it is the real signatures. but would they be worth anything, at any time?
