Where would you sell your vinyl collection?


So....
Unfortunately after buying and fixing up a new house and finding we have another kid on the way the time has come to part with my vinyl collection. I just finished putting everything on Discogs. I ended up with 440 albums with Discogs suggesting the lot is worth a decent bit. Is Discogs pretty accurate value wise? Most are audiophile records: Mofi, Classic Records, Speakers Corner, Record Store Day Exclusives, box sets, numbered editions, 45 RPM, 180 or 200 gram, etc. etc. Heavy on classic Rock, Jazz and Blues. I’ve been collecting for ten years and have never sold a record. Most have only been played a couple times and been hanging out on bookshelves. Would you recommend selling on Audiogon? Discogs? Ebay? Amazon? Would it be possible to sell the whole lot at once for the sake of simplicity? I live in NJ not too far from Princeton Record Exchange which buys collections but I’m assuming their offer would be super low relatively speaking as a reseller? All suggestions needed and welcome I need to find the best way to make some cash for the family sooner rather than later. Thanks!

Thanks so much for all the insight I really appreciate it! I’ll check out Popsike as well I had never heard of that site before. Yeah I was amazed by how many versions so I matched catalogue numbers with all run-off groove etchings. It took forever. 
Had no time today to comment as real busy at work but here goes my 3 cents.
As a very long time seller/buyer on eBay and relatively fresh Discogs seller/buyer I feel I have a little perspective on both.

From what I have seen, Discogs gets a slightly better audience than eBay and you are likely to reap higher prices but the wait may be longer and you better describe it and the exact copy etc to the tee!

Ebay obviously has a massive audience so good exposure  and if you price it fairly and competitively it is likely to move more quickly. However eBay is also more likely to suffer more potential problems vis refunds/returns as it is all about buyer protection. Like Elvis seller protection has left the building!

On both I would advise listing with best offer option but not for the reasons others have already mentioned. By giving the best offer option, the majority of buyers are going to take that route. That gives YOU, the seller , the opportunity to research THEM, the buyer, check their feedback etc and if anything looks suspicious then decline their offer and never have to deal with them or their potential problems. This has worked well for myself over the last 20 years.
Good luck out there, its a cruel world...lol
