Seriously though I’m in the camp that there isn’t likely to be a premium on this. Sure, once in a blue moon you’ll find the right buyer to pay the premium but most likely you’ll get 6x whatever a booster box is going for IMO. Theres just orders of magnitude more buyers the more you break it down. Hell I still see most WOTC era boxes selling at or less than 36x guaranteed unweighed packs would sell for due to similar reasons. Some day it should change but I’m not sure it will anytime soon for some of these boxes.
Even take an extreme example and say someone has a case of ex deoxys I dont see a premium over 6 mint boxes.
There would certainly be a premium on the case if they could prove the source. I doubt they have one, but imagine if this person had the receipt or memo/invoice from distributor. That would absolutely be a premium. If someone knew for a fact they had a genuine sealed case it would be a more valuable collectible and piece of history. To answer @lyleberr, unfortunately this is the only CERTAIN way to prove authenticity. Other than break it. I would argue this is harder to fake than a box reseal though. There are number markings on the box and the sticker could be analyzed by its barcode and make # by a serious expert. Basically WOTC.
The box has 4 top flaps. Two long ones under the tape and 2 short ones on the sides. If you cut one of the top flaps loose, you can lift it and see booster boxes but not remove them from the box because the other 3 flaps which are partially obstructing them. You see the sealed boxes inside not some Styrofoam and pennies or some random stuff made to weigh what the 6 boxes would weigh. That’s why he partially opened the case.
