I know nothing about the Leafs mask, but I can't see the Mylec street hockey mask even with it being considered "vintage" as this point (looks like a model from the mid 80's) could be worth any more than $10-$20. Now that I've put it out there, I'll be proven wrong and that there's some big market for Mylec stuff from the 80's. If only I had known, I would have kept my stash of Air Flow sticks!
