That's what the box sells for on TCGplayer today. We have prices for the cards inside, but they add up to far more than the box costs, which usually means we've matched a card to the wrong rarity or the pull rates are off. We're checking it before we give a verdict.
Estimated contents: nobody has published measured pull rates for this box yet, so we use those of boxes with the same pack layout. Treat the numbers as a rough guide.
