How Hard is it to Get Mats Sundin?

I know Sundin,as with many other hockey players usually have no problem signing for kids,according to a friend in Toronto....the issue sometimes "older" people face, that is-older teens on up..-especially when you approach with things like pucks-.....or sticks,or photos...or jerseys...is they ume you are probably a memorabilia dealer and the stuff is probably just going to end up on eBay,that its not for "you"..so they p by a lot of adults with the stuff...
