Here are the odds i worked out based on cases and cards listed in this thread and on the boxes, i would say an educated guess, but it is probably just a guess...
Number of cases 540, number of boxes 6,480. packets per case 432.
Legend signature (4) numbered to 110. thats 1 per case, leaving 100 other case cards, as mentioned by phantom sports.
or legend signature (4) numbered to 180 is 1 per case.
draft pick signature (18) numbered to 180 and certified signature (18) numbered to 180, that's 1 per box, a certified or draft not both.
afl hall of fame limited edition (750 numbered sets) of 30 players is 1 per 12 packets or 3 per box. there are also hall of fame common cards that are not numbered, as per the last release with the parallel limited edition red backed numbered cards.
if premiership predictors are gold and platinum and 1 per box is 360 cards per team, so there could be 300 gold and 60 platinum per team.
if premiership predictors are 1 per 2 boxes then this is 180 cards per team, maybe 150 gold and 30 platinum.
medal cards (5) 1 per 216 packets (6 boxes)
Influential /30 (18) 1:432 packs from ECH
Case cards greene and cloke, which is 220 numbered cards each, and 50 signed cards each. odds of a signature case card are 1 every 5.4 cases.
leave the parallels, all australians, future hall of fame (could be as bad as the sheehan selects in ff) a bit of a tossers set, and any other subsets to someone a little smarter than me.
