If this is any kind of sign, then maybe we're in for one hell of a ride. These prices are really out there as far as I'm concerned. But you have to wonder, are they buying these to use, or are they buying them just to say, "Hey, lookie what I got?"
I see too much of that in any collecting forum. Someone will buy something only because of it's collector valus and vever open it. The contents could be a bunch of blank paper for all they know, but because they don't want to ruin the collector value, they'll never really know for sure.
Then too, what condition are the floppy disks? Have they been stored properly, or has someone placed them too close to the TV? Again, we'll never know for sure unless the buyer opens it up, and by doing that, they ruin the collector value. Double edged sword!
