If you have the patience, you should track the "completed" listings on ebay for each album you have for guidance.
But it's almost impossible to say w/o knowing what you have & the condition. I've sold off old rock LP's. Many wouldn't bring over 25cents & I donated to the Salvation Army. I sold one batch of 20 LP's on craigslist for $15. One Zappa album brought $20. And so on.
My guess is, you might go thru a lot of dues listing, researching, & shipping these to maybe clear $50.....
