just purchased a small collection and found a box of this:

Football

1976 Rack Packs 42 cards per pack 14 packs (i listed one on the bay)
1979 Rack PAcks " " (listed one on the bay)
1980 2 hobby boxs sealed with 24 rack packs in each box=48 packs

Baseball

1974 Rack Pack 42 cards per pack 2 packs (i listed one on the bay)
1976 Rack Pack 42 cards per pack 14 packs (i listed one on the bay)
1981 2 hobby boxs sealed with 24 rack packs in each box= 48 packs

the ones i listed on the bay are doing really well. especially the 76 stuff. i would consider tradeing a few sealed packs. None are searched/opened, and i plan on keeping it that way.

on the beckett forums a average price i was told was

football:
76 per pack 150-200
79 per pack 30-50
80 per box 100-120

baseball
74 per pack 100-120
76 per pack 100-150 last one i seen on the bay sold for 103
81 per box 100-120

i can get you scans of packs if your seriously interested, also if you'd like to see the ones i have listed my bay id is:
