I got a huge box of 1960's 45 records, now what?

I just got a huge box of 45's from an old closed warehouse that was liquidating it's decades forgotten merchandise. I did not bother looking through all of the titles, judging from the condition I found them in, I could probably get them at a good price. I got the whole box dirt cheap, literally. Most of them were covered in dust and debris, some were cracked or broken. I started cleaning them gently. Just like I remember cleaning my records when I was a kid. I washed them gently with running water and cleaned them thoroughly with alcohol, they were filthy. I was able to restore many of them to very good + condition. Now I am listing the best and rarest ones one ebay.
