Ken,
My opinion is that you should list your LPs in small lots, say 5, 10, or 20 at a time, set a price for them and see what happens. You could try to sell them as a lot, or individually, or both. Then you will have a better idea of what moves and what doesn't. The auction may be best to try and sell what it left over.
However you decide to do this be prepared, as Mothra posted, for this to take some time. The only work you need to do is the listing and then the shipping. Be patient and I think you can get a pretty good return.
