Very nice find! Wow! Even the culls aren't too bad! I imagine if I was there, I could pick about 100 out of those crates that would interest me. I agree with what someone said earlier. Pick all the stuff you know you don't want, duplicates, and stuff you know but aren't interested in, and put on a garage sale on them for $2 each. You would be surprised at what sells!
I am on the very end of a lot of 750 records. I kept about 300 in my collection and got most of my investment back from the first 200 that sold. I've now doubled my money, and I'm about ready to donate what I have left. I got them in spring. I just put an ad up and let people pick through it. Started with pricing of $20, $10, and the rest $5, and now I'm at $2 each.
