My guess is that they are weighing them or measuring them. I am guessing that the thickness of the pack or the weight of the pack would be different for packs containing autos or GU cards. But that is just a guess on my part. Seems shady to me which is why I would never buy one.
At one of the Nationals in California......Dealer had packs of 1993 Topps Finest and a sign indicating a refractor was in every pack....packs were about $25.00...when this product first came out....there was one refractor per box! There was 24 packs per box....There was about 3 or 4 watching ...as one person brought a pack...and sure enough..there was a refractor in the pack! Only way this could happen......brought some low graded refractors and insert them into the pack and then resealed them. Best regards, David
We noticed on his table...he had about twenty to twenty refractors....all badly off center...and not one big name player.......guy pulled a George Bell refractor that was badly off center.....we needed in his display.....he had about 4 or 6 more George Bells! Best regards, David
