The set with MLB Authentication - which authenticated the home jerseys to game 6 and the road jerseys to game 5 - were sold directly via Steiner and also via MLB Auctions. Having had a few of the homes in my possession, I can verify, for the ones I saw, that they had extensive use - I did photomatch a few coach's jerseys to game 6 at Yankee Stadium as well so I was very comfortable with that set based on the small sample I had the pleasure to handle.

I do believe there are 1 or 2 more jerseys from this set at Steiner including this Gaudin where you can see the MLB hologram authenticates it to Game 5:
