@keninrockwall: There is a way to grade your vinyl. It’s known as the Goldmine standard. Carefully rate each album according to this scale and list them as a whole collection, or individually. There are many on this site, who may be interested. Be cautious in your ratings. I bought a collection from an Agoner years ago and received nothing but crap. I had to put my want for a refund into arbitration, but did receive a refund, which included return shipping charges. I have bought several LP’s on this site which are exceptional.
