To describe a microcosm of this line of thinking, let’s take Pokémon cards. Packs containing a (foil/holo) card weigh more. A sealed box of packs is theoretically a gold mine. But how do you establish that the presealed box wasn’t raided and resealed? A whole system of trusty discoverers and buyers play hand in hand.

Individual packs will always be looked at with doubt, since they’ve probably been weighed and sorted.
