I have come across the Autograph City Mystery Boxes on Facebook from a YouTube video on my feed, I am interested in finally buying one with all the great successes coming out of the boxes.  It's almost too good not to be true with so many of the great names coming out of them.  Does anyone know anything about the seller or where the inventory comes from?  There's just nothing wrong or imperfect about any of there items, every item is a full namer or fuller signature than anybody else and every item is done in the perfect spot or marker/pen used.  Everything is mostly authenticated by Beckett or PSA (pre Steve Grad departure), is this because they do so much business with them so everything passes or is everything actually legitimately, 100 percent authentic?  Am I overthinking it and should i go ahead and buy a box to see what comes out of it and know for sure its 100 percent authentic?
