Wow, got more interest than I thought, thanks to all who reached out on this thread or via PM. I'm primarily looking to move it all as a lot, if I can't work out a fair deal for the whole thing I'll contact folks who have specific player/team wants. I'll try to work on a more detailed list for those who are really interested, but can share a quick view for now:
The stacks in the top row are (from L to R) '81, '82, and '83 ... the next two rows are all '84... followed by in order by two stacks of '85, and the remaining are '86, '87, '88, and '89 respectively. The taller stacks are around 40-50 cards high, so I believe there's around 500 in the total, almost all unique but I may have picked up a dup or two. I don't recall picking up any high-end RC's, a fair chunk of no-name players, but there are some HoF'ers in the mix and some unmarked checklists.
I haven't really looked into what's the going rate on bulk lots like this, if you've got an offer in mind lmk, I don't want to ask for a silly amount so I'll do a little research tonight as well to see what might be fair comparables.
