I don't think you really need advice. I think you need a buyer. This is the wrong place to find a buyer for those records. You're either going to have to ship them (it's easy, look it up) or dump them off at a record store. Possibly look on craigslist for a buyer.  Good luck.

So... Thanks all for your advice! Especially those on topic. Condoleances appreciated mainly because it says good things about those of you who left them and the forum. Re the ribbing, I'm on enough forums to recognize the jargong among the initiated. Same goes for discussions sliding into meta territory about the forum, what it was, is and should or shouldn't become...
In the end, I'll try for the advice from NapalmBrain and SomethingVinyl, post my current list to ebay and see if anyone bites.  Current list as following, in case anyone's interested. May update it with additional items. Cheers everyone, and thanks again! I just may stick around this forum  

You should have been here when the colour changed.

"representative subset for extrapolation sufficient"

Yes.

As others have noted, if you've got the time and energy to put into it, try to sell the valuable records individually on Discogs and then take the rest to a local record store that deals in classical recordings.  If you can't think of such a store, you might consider asking local music teachers.
My condolences for your loss.

if it's mostly classical, discogs is a terrible place to sell. The prices are completely inaccurate on most titles, barring a couple highly sought after titles like witches' brew or the soria set of the royal ballet gala. I would recommend ebay, search completed sales or popsike to see what they went for. The big 4 labels are mercury living presence, rca victor (shaded dog and red dog labels), EMI and london/decca (FFRR or FFSS). Also some Deutche Grammophone (mostly the tulip label). Mostly only stereo pressings are worth anything, the exception being titles originally recorded only in mono. There are other boutique labels and even some specific titles on budget labels that are worth money but these are broad guidelines for evaluating a classical collection for sale. Sorry about your dad, good luck

This. Honestly, I would just unload them at a local record store and save yourself the time and effort. 

Sorry for your loss.
 

List them on Discogs, you'll get a better idea what each is worth. If that's too much work just list the ones you know are valuable and sell the other stuff to a local record store.

Either look them all up individually or dump them at a store. The problem with classical is unless you're selling to a store specializing in classical you are going to get a very low offer, possibly they may even be rejected. I say look them all up then post the higher dollar ones individually and the rest in bulk. 

Some of that shit goes for crazy ass amounts of cash.

Take them to a record store and accept whatever offer they give you. 

If you don't want to put effort into it, sell them to a trust worthy local store.
Else look them up individually on Discogs.com and try to sell them there.
