I have had some great success removing cards from pages. I have also experienced, basically, utter failure. I once removed a bunch of cards so fast it was amazing. I put two pages in two separate Pyrex Lasagna dishes and stepped away for a quick cigarette. Just that fast, they all floated free and I was on to the drying process. On the other hand, I have had some that simply wouldn't budge, period. The adhesive and even the way it was glued can make all the difference.
However, what I see here is 7 second tier HOF guys and a SL-er mixed in with 40-some commons. More than a couple already have condition issues, assuming an easy release. If there is any back damage once they come free, it is that much worse. If the winning bidder is a collector versus a flipper than he might come out "OK". Rarer backs could tip the scales. A pile of Piedmonts and Sweet Caps would be a tough hurdle to deal with.
I see that the winner is a board member. Perhaps he could let us know how the soak goes.
