Authentic memorabilia is incredibly important, and not just for the fact collectors want pieces of memorabilia that the player actually used. Box prices are steep and collectors are under the impression that part of the reason we're paying those high prices is because companies have to buy expensive game used equipment. If they are passing off fake jerseys and charging us premium wax prices that's a huge problem.
I lost faith in UD memorabilia long ago and it's only getting worse. ITG is the best there is when it comes to authenticity and so far so good from Panini, at least with hockey.
