Do people even buy vinyl anymore?
Should I sell them individually via say discogs or ebay?
Should I save my time and get rid in one job lot?
Thoughts please 
Yes, people still buy vinyl (I do) and sales are up 55% this year.
Whether you sell them one at a time or all together will depend on what you have.
You will make more money selling individually, but only if people actually want the record.
The best bet is to cherry pick the collect and sell on ebay, then off load the rest to some idiot.
Ok cool.
Looks like discogs is the way to go!
