15,000 LP's - What to do with records?

I agre with Narrod - if you try to unload these as a lot you are going to come up short. Very short. But you have to weight that against the hassle of moving, cataloging, posting, selling, shipping and tracking payments for all of these.

Hell, I'll bet that there are lots of guys here on Audiogon who will give you more than .10 a record for the lot, sight unseen. If it were me I might just put up an auction and see what happens. You can always set a reserve - say $1 an LP. I guarantee that that's more than any retail store will offer you.

Where are they located, and how would you ship them as a lot?

Sell them to Europe - a good collection here is worth more than 1 usd a record ...

SteveAudio, standard A4 paper box will hold about 50 albums. 15,000 records would be 300 boxes. That's 6 boxes wide, by 10 deep, by 5 high. It's about 3000kg of records. And in listening terms, it is about 10 sides every night, including vacation, for four years.

T-bone -- your math's a bit optimistic. At 10 sides/per (i.e. 5 records) that's more than 8 years!:) Regards

I bought 1200 various titled LPs in varying condition (junk to new) at $150 from ebay. It was a local sale.
I salvaged about 100 for my own collection. I sold some I don't care at Amazon for $5~$30.
I would suggest you to put a bulk of 100 LPs on ebay according to their genre. Jazz and classicals with major recording company will pay most ($2+ per LP). Easy listening may not pay as much.
