Are the individual boxes sealed? And, are the redemption cards plastic or metal? I'm concerned if they're metal, people *might* try weighing the boxes and finding ones that are heavier as happened with the "Inverted Jenny" aircraft stamp from the USPS a couple of years ago where a redemption card was randomly inserted into packs and a few of the dealers were walking away with the prizes.
I'm referring to the secondary market, not this market.
A case has 4 smaller sealed boxes of 12 boxes each with 2 packs of cards.
I opened some, catalogued and weighed the 12 boxes, individual boxes (two packs), and individual packs.
In my small sample size there was no pattern for the location of redemption cards, refractors, MR, or CF cards within in the full case, or smaller 12 box case.
The redemption cards are normal cardstock like the base cards.
Boxes (of two cards) weighed about 44-45g, most at 44g containing two 14g packs.
*Most of the time* a 45g box had one pack that was 15g, but not always.
Packs were always either 14g or 15g.
Packs that weighed 15g *usually* had a refractor (orange, green, purple, red etc.) always in the third spot of five cards.
Packs with MR, CF or redemption card were always 14g. MR, CF, and redemption cards were either 2nd or 4th spots.
This means packs with only base cards/HF/CS are the same as the ones with redemption cards. So purchasing on the secondary market is still a big risk with really no reward, unless you are looking for the refractors I guess, then 15g packs are higher chance of a good pull.
FWIW, the bottom pack in the box (if you open the tab up) *usually* but not always was the one of two with the crystal sparkle card. Holofoil cards are the 3rd card, crystal sparkle are the 2nd card if there is one.
Hope this helps. Happy hunting!
