What is the best way to sell a record collection?

Sell a small amount at a time. I would put of for sale choice recordings along with not so choice bundled together. Where are you located I would love to cherry pick this tree. I would not sell as a total collection you will not get full price or even close. Also avoid at all cost record stores they will give you pennies on the dollar. Your better off selling them on Audiogon just a couple at a time and give off a chance to nibble at this treasure.

I sold mine in lots of ten to twenty as Schipo suggests. But, and this a big but, I sold 500 lps not 3500. It was a bit of a pain. Selling 3500 will be a major pain.
Search the archives here as this question comes up monthly.

if you have the time....individually on ebay. otherwise, you buy them from your dad.

Send me an email. I may be interested in buying.

Also send me an email, I may be interested in the whole collection only. I do admit that selling piece by piece will get you a better price, but it may not be worth the hassel.
