You are correct in that there may not be any takers. You can maybe look into upgrading/repairing the laptop (new battery, RAM upgrade, keyboard repair) and donate it to someone needy. Not quite sure who might it be but it's atleast better than getting junked.Not sure if there will be takers for this, but I have a 8+ yr old laptop (not sure about the purchase date, need to check invoice).
In terms of valuation honestly I don't see this selling for more than 5k or so. I would argue 5k is also a high price for this. I might be wrong so YMMV.
