i call FAKE! for the jerry's and its hard to fake D&D decks
I'm not sure about the D&D decks but the jerry's might be real, the seals are placed slightly to the left or right (I forgotten which side) on one of the pictures, I read in another post that this was because the seals were small hence sticking it at the centre would not be 'safe' thus placing it on the sides so as to secure it more.
